Most of these changes are places where lifetimes were named, but can be
elided. Then a few cases where a lifetime was elided, but actually
resolves to a named lifetime. So lots of lifetimes.
This is the `v0.1.x` branch sister PR to #3164 (for the `master`
branch), since `clippy --fix` on another branch is a much better way to
apply these changes than backporting.
Clippy in 1.80.0 alerted us to the fact that `SerializeField` was never
constructed (and due to its non-`pub` member, it can't be constructed
outside the `tracing-serde` crate where it's from).
This change fixes the definition to hold a reference to a `Field`, which
is what the other `Serialize*` types do. It also implements `AsSerde`
for this type and uses it inside the `SerializeFieldSet` type.
As a bonus, Clippy is now also happy that the type is constructed.
The example collector in the `tracing-serde` crate was also renamed from
`JsonSubscriber` to `JsonCollector`.
Some additional doc formatting issues in `tracing-subscriber` were fixed
so that list items that run to multiple lines are correctly indented.
With the release of Rust 1.74, there are some new or modified clippy
lints that need adaption in the code.
The main change was the removal of the `private_in_public`.
https://rust-lang.github.io/rfcs/2145-type-privacy.html
Then two more changes were required, in one case to adhere a lint and
the other to allow it. When talking about what an "application" needs to
do when setting up `tracing-error`, it makes sense to include `fn
main()` in the doctest, even though the lint recommends against it.

## Solution
Fix the warnings based on the suggestions for Clippy.
## Motivation
I've wanted to serialize fieldset of current span.
## Solution
Expose already existing `SerializeFieldSet` for users by implementing `AsSerde` for `FieldSet`.
This updates all crates' MSRVs to 1.49 if they were not already greater
than that (`tracing-appender` is at 1.53). Rust 1.49+ is required to
update `parking_lot` to v0.12 (see #1878). Also, `futures-task` (which I
believe is only needed as a transitive dep) now needs 1.45+, so this
also fixes our CI build.
Because `tracing-opentelemetry` previously required 1.46.0, it had a
separate CI MSRV job. Since 1.49.0 is greater than 1.46.0, the separate
check for `tracing-opentelemetry` is no longer needed.
In the process, I removed deprecated uses of
`core::atomic::spin_loop_hint`, which is replaced with
`core::hint::spin_loop` in 1.49.
This branch introduces support for `valuable` in `tracing-subscriber`'s
JSON formatter, and in `tracing-serde`, using the `valuable-serde`
bridge.
This allows the `fmt::Json` subscriber to actually record `valuable`
values as structured JSON. Here's an example, where a field is first
recorded using `fmt::Debug`, and then again using `field::valuable`:
```
:; RUSTFLAGS="--cfg tracing_unstable" cargo run --example valuable_json | jq

}
}
},
"target": "valuable_json"
}
```
As a side note, this branch also nicely validates that recording `Valuable`
values from a subscriber is actually possible, which the previous valuable PR
didn't have an example of.

## Motivation
Tracing is a really useful framework but a lack of floating point value
support for the core visitors means these get coerced unnecessarily to
strings.
## Solution
This change adds support for floating point (`f64`) visitors.
This branch fixes some minor RustDoc issues. In particular:
- The `broken_intra_doc_links` lint was renamed to
`rustdoc::broken_intra_doc_links`. This generates a warning, since the
old name was deprecated.
- `ignore` code blocks are specifically for _Rust_ code that should not
be compiled, not for other text blocks. We were using `ignore` on JSON
blocks, which generates a warning.
- A bunch of links in `tracing-subscriber`'s RustDocs were broken. This
fixes that.
I also changed the Netlify configuration to run with `-D warnings`, so that
we can surface RustDoc warnings in CI builds.

This backports PR #991 to v0.1.x. This is primarily necessary for the MSRV
bump, since some dependencies no longer compile on Rust 1.40.0.
This has already been approved on `master`, in PR #991, so it should be
fine to ship.
## Motivation
This will avoid breaking CI on new releases of clippy. It also makes the
code a little easier to read.
## Solution
- Convert `match val { pat => true, _ => false }` to `matches!(val, pat)`
- Remove unnecessary closures
- Convert `self: &mut Self` to `&mut self`
This bumps the MSRV to 1.42.0 for `matches!`.
The latest version of rust is 1.46.0, so as per
https://github.com/tokio-rs/tracing#supported-rust-versions this is not
considered a breaking change.
I didn't fix the following warning because the fix was not trivial/needed
a decision:
```

As a side note, this found a bug in clippy 😆https://github.com/rust-lang/rust-clippy/issues/6089

In order to get a compiler warning (or error) when links are broken.

- [x] add `deny(broken_intra_doc_links)`
- [x] add a note to the CONTRIBUTING.md documentation on building docs locally

### Added
- `SerdeMapVisitor::finish` to complete serializing the visited objects
(#892)
- `SerdeMapVisitor::take_serializer` to return the serializer wrapped by
a `SerdeMapVisitor` (#892)
Thanks to @bryanburgers for contributing to this release!
This changes the logo to a wordmark. This should be consistent
with the ones for all the other Tokio crates, when we add them
elsewhere.

## Motivation
JSON is a structured format, so the order of the fields should be
unimportant.
However, sometimes the JSON output is read in non-structured or
semi-structured contexts, and sometimes the output is truncated. In
those situations, when the spans and the current span are serialized
before the fields and the message, it makes it very difficult to see
what is going on.
## Solution
By serializing the "fields" key before the "spans" and "span" keys, this
information is more likely visible when the payload is shown raw and
gets truncated.
Systems that parse the JSON as structured data should be unaffected
because of the nature of JSON.
Fixes#891
## Motivation
PR #934 fixed a bug in the CI configuration where MSRV checks were not
being run correctly. After this was fixed, it was necessary to bump the
MSRV to 1.40.0, as the tests were no longer actually passing on 1.39,
because some dependencies no longer support it.
While updating the documentation to indicate that the new MSRV is 1.40,
I noticed that the note on the MSRV was located inconsistently in the
READMEs and `lib.rs` documentation of various crates, and missing
entirely in some cases. Additionally, there have been some questions on
what our MSRV _policies_ are, and whether MSRV bumps are considered
breaking changes (see e.g. #936).
## Solution
I've updated all the MSRV notes in the documentation and READMEs to
indicate that the MSRV is 1.40. I've also ensured that the MSRV note is
in the same place for every crate (at the end of the "Overview" section
in the docs), and that it's formatted consistently.
Furthermore, I added a new section to the READMEs and `lib.rs` docs
explaining the current MSRV policy in some detail. Hopefully, this
should answer questions like #936 in the future. The MSRV note in the
overview section includes a link to the section with further details.
Finally, while doing this, I noticed a couple of crates
(`tracing-journald` and `tracing-serde`) were missing top-level `lib.rs`
docs. Rather than just adding an MSRV note and nothing else, I went
ahead and fixed this using documentation from those crate's READMEs.

Now that the new https://tokio.rs is live, we can add the new Tracing
logo to the RustDoc!
I also added a couple missing `html_root_url` attributes in published
crates.

## Motivation
Currently, most crates in `tracing` are configured to deny all compiler
warnings when compiling tests. This means that if the compiler reports
any warnings, the build will fail. This can be an issue when changes are
made locally that introduce warnings (i.e. unused code is added, imports
are no longer needed, etc) and a contributor wishes to test an
incomplete state to ensure their changes are on the right path. With
warnings denied, tests will not run if the project contains any
warnings, so contributors must either fix all warnings or disable the
deny attribute. Disabling the deny attribute when making changes locally
has become a fairly common practice, but it's error-prone: sometimes,
the deny attribute is commented out and then accidentally committed.
## Solution
This branch removes all `#![deny(warnings)]` attributes, in order to
allow code with warnings to compile and be tested locally while changes
are in progress. We already have [a CI job][1] that checks for compiler
warnings by trying to compile `tracing` with `RUSTFLAGS="-Dwarnings"`.
If we make this CI job required rather than allowing it to fail, we'll
still be able to ensure that no code with warnings is merged.
Additionally, I've updated all crates to use the same consistent list of
lints to apply in the `#![warn]` attribute. Previously, some crates
warned on more lints than others, which is not great. I've fixed all the
new warnings produced by the additional lints.
* chore: consistent warnings, don't deny locally
* fix warnings from new attributes
* remove warning that no longer exists on nightly

## Motivation
A formatter for JSON output.
## Solution
Enable `json` feature from `tracing-subscriber` crate. Instantiate a new formatter with JSON output:
```rust
let subscriber = FmtSubscriber::builder()
.json()
.with_env_filter(EnvFilter::from_default_env())
.finish();
subscriber::set_global_default(subscriber)?;
```
Closes#218
This PR changes the field names to better represent the `is_span` and
`is_event` values being serialized in `Metadata`. Out of band, we noticed the
previous field names did not correspond with the data we were serializing
for those 2 functions.
See #95
This branch renames everything from `tokio-trace` to `tracing`.
Unlike PR #98, the nursery crates still depend on the crates.io
versions of `tokio-trace` and `tokio-trace-core`, but renamed
to `tracing`/`tracing-core` in `Cargo.toml`. We can update the
nursery crates to depend on local path dependencies in a
subsequent PR, as that will require making code changes to the
nursery crates.
This branch _also_ updates the minimum Rust version to 1.34.0,
to the shock and horror of the millions of `tracing` users still
on Rust 1.26.0. This was necessary in order to allow renaming
crates in `Cargo.toml`, and to resolve that not using the `dyn`
keyword is now a warning on nightly.
