Trait ResultExt

pub trait ResultExt<T, E> {
    // Required methods
    fn ok_or_log_error(self) -> Option<T>;
    fn ok_or_log_error_once(self) -> Option<T>;
    fn warn_on_err_once(self, msg: impl Display) -> Option<T>;
    fn unwrap_debug_or_log_error(self) -> Option<T>;
}

Required Methods

fn ok_or_log_error(self) -> Option<T>

Logs an error if the result is an error and returns the result.

fn ok_or_log_error_once(self) -> Option<T>

Logs an error if the result is an error and returns the result, but only once.

fn warn_on_err_once(self, msg: impl Display) -> Option<T>

Log a warning if there is an Err, but only log the exact same message once.

fn unwrap_debug_or_log_error(self) -> Option<T>

Unwraps in debug builds otherwise logs an error if the result is an error and returns the result.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
