This prevents diagnostics being rendered like `serde_core::ser::Serialize`
and `serde_core:🇩🇪:Deserialize` in projects that have no direct
dependency on serde_core.
The attributes make error messages arguably sometimes worse than
pre-serde_core by always rendering `serde::Serialize` and never
`Serialize` when `use serde::Serialize` is in scope, which rustc's
default message construction knows to recognize. But this is probably
negligible.
I explored the alternative of setting `[lib] name = "serde"` in
serde_core/Cargo.toml which also prevents `serde_core::ser::Serialize`
in messages, but has the unwanted effect of also inserting the following
noise into every such error:
note: there are multiple different versions of crate `serde` in the dependency graph
--> $WORKSPACE/serde_core/src/ser/mod.rs:225:1

= help: you can use `cargo tree` to explore your dependency tree
The "this is the found trait" pointing to `IdentifierDeserializer` seems
like a compiler bug...
In the 2024 edition of Rust, `serde`s macros for `serialize_with` can
lead to a temporary lifetime error such as:
```
error[E0716]: temporary value dropped while borrowed
--> my-binary/src/main.rs:6:10
|
6 | #[derive(MyDerive)]
| ^^^^^^^-
| | |
| | temporary value is freed at the end of this statement
| creates a temporary value which is freed while still in use
| borrow later used by call
| in this derive macro expansion
|
::: /private/tmp/life/my-project/my-macro/src/lib.rs:6:1
|
6 | pub fn my_derive(_input: TokenStream) -> TokenStream {
| ---------------------------------------------------- in this expansion of `#[derive(MyDerive)]`
|
= note: consider using a `let` binding to create a longer lived value
```
This is because the macro code takes a reference to struct inside of a
block, which then goes out of scope when `serde` passes it to a
function.
To resolve this, we move the reference to outside of the block, to
ensure that the lifetime extends into the function call.

Allow deprecated in the `Serialize`/`Deserialize`
derive implementations. This allows you to
deprecate structs, enums, struct fields, or enum
variants and not get compiler warnings/errors
about use of deprecated thing. We only do this
if `#[deprecated]` or `#[allow(deprecated)]` exist
on the root object or the variants of the root
object (if it is an enum).
Resolves#2195
Updated the Cargo.toml files for test suites and a link in the README to use Rust edition 2021 instead of 2018. This ensures compatibility with the latest Rust features and standards.
