Trait LogDebugErr 

pub trait LogDebugErr<T, E: Debug> {
    // Required method
    fn err_debug_log(self, level: Level) -> Self;

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

Logs debug-formatted errors when debug assertions are enabled.

Successful values pass through without producing a record. With debug assertions disabled, errors also pass through without producing a record.

Required Methods

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

Logs a debug-formatted error at level and returns the original result.

The error is formatted with Debug when debug assertions are enabled. Successful values always produce no log record.

Provided Methods

fn log_debug_err(self) -> Self

where Self: Sized,

Logs a debug-formatted error at the error tracing level.

LogDebugErr::err_debug_log supplies this convenience form with Level::ERROR. Logging occurs only when debug assertions are enabled, and 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".
