-//! ## Supported Rust Versions
-//!
-//! Tracing is built against the latest stable release. The minimum supported
-//! version is 1.60. 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.
