pub trait FileLoggerFuncTrait<T: AsRef<str>>:
    Fn(T) -> String
    + Send
    + Sync { }

Trait for log formatting functions.

Defines the interface for functions that format log data. Implemented automatically for any compatible Fn(T) -> String.

In older versions of Rust, dyn compatibility was called "object safety".

Implementors

impl<F, T> FileLoggerFuncTrait<T> for F

where F: Fn(T) -> String + Send + Sync, T: AsRef<str>,

Blanket implementation for any function matching FileLoggerFuncTrait signature.

This allows any compatible closure or function to be used as a log formatter.
