Module snafu::guide::compatibility

Rust version compatibility

SNAFU is tested and compatible back to Rust 1.34, released on 2019-05-14. Compatibility is controlled by Cargo feature flags.

rust_1_46

default: enabled

When enabled, SNAFU will assume that it’s safe to target features available in Rust 1.46. Notably, the #[track_caller] feature is needed to allow Location to automatically discern the source code location.
