## Motivation As discussed in #292: > A follow-up to remove an explicit dependency on `proc-macro2` would be > great, though, as it would make it easier to avoid pulling duplicate > versions of that crate. ## Solution Remove `proc-macro2` as a direct dependency and replace usages of types from it accordingly. - remove `proc-macro2` as a direct dependency - replace usage of `TokenStream` from `proc-macro2` with `impl ToTokens` from `quote` - remove usage of `Span::call_site` as that is used by default for the `quote!` macro
tracing-attributes
Macro attributes for application-level tracing.
Overview
tracing is a framework for instrumenting Rust programs to collect
structured, event-based diagnostic information. This crate provides the
#[instrument] attribute for automatically instrumenting functions using
tracing.
Note that this macro is also re-exported by the main tracing crate.
Usage
First, add this to your Cargo.toml:
[dependencies]
tracing-attributes = "0.1.0"
This crate provides the #[instrument] attribute for instrumenting a function
with a tracing span. For example:
use tracing_attributes::instrument;
#[instrument]
pub fn my_function(my_arg: usize) {
// ...
}
