  -## Supported Rust Versions
  -
  -Tracing is built against the latest stable release. The minimum supported
  -version is 1.42. The current Tracing version is not guaranteed to build on Rust
  -versions earlier than the minimum supported version.
  -
  -Tracing follows the same compiler support policies as the rest of the Tokio
  -project. The current stable Rust compiler and the three most recent minor
  -versions before it will always be supported. For example, if the current stable
  -compiler version is 1.45, the minimum supported version will not be increased
  -past 1.42, three minor versions prior. Increasing the minimum supported compiler
  -version is not considered a semver breaking change as long as doing so complies
  -with this policy.
