Description

Summary

Due to the following errors were reported:

error: expected identifier, found `$`
   --> src/common/orders_pool/pools/orders_pool_processor.rs:101:25
    |
101 |                     use $crate::__macro_support::Callsite as _;
    |                         ^ expected identifier

I cannot apply cargo clippy --fix

The problem is under tracing-0.1.41/src/macros.rs:

use $crate::__macro_support::Callsite as _;
Reproducer

I tried this code:

tracing::error!(
                    "Error during order pool creation: {:?}",
                    error
                )

I expected to see this happen: cargo clippy --fix will work as expected

Instead, this happened:

error: expected identifier, found `$`
   --> src/common/orders_pool/pools/orders_pool_processor.rs:101:25
    |
101 |                     use $crate::__macro_support::Callsite as _;
    |                         ^ expected identifier

Research direction

Reproduce the failure with the reported tracing::error! call and cargo clippy --fix using the listed Rust version. Inspect tracing-0.1.41/src/macros.rs and the generated location in src/common/orders_pool/pools/orders_pool_processor.rs:101. Done means cargo clippy --fix no longer reports the unexpected $ identifier error.
