Trait ErrLog 

pub trait ErrLog<T, E>
where
    E: Display,
{
    // Required method
    fn log_err(self, level: Level) -> Self;

    // Provided method
    fn err_log(self) -> Self
       where Self: Sized { ... }
}

Logs display-formatted errors while preserving their result.

Successful values pass through without producing a log record. Error values are inspected at the requested tracing level and remain unchanged.

Required Methods

fn log_err(self, level: Level) -> Self

Logs an error at level and returns the original result.

The error is formatted with fmt::Display. An Ok value produces no record and is returned unchanged.

Provided Methods

fn err_log(self) -> Self

where Self: Sized,

Logs an error at the error tracing level.

ErrLog::log_err supplies this convenience form with Level::ERROR. The original result is returned after inspection.

Dyn Compatibility

This trait is not dyn compatible.

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