For logging a Result when an Err is encountered.

Required Methods

fn error(self, context: impl Display) -> Result<T, E>

Log the context as an “error” if the Result is an Err.

fn warn(self, context: impl Display) -> Result<T, E>

Log the context as an “warn” if the Result is an Err.

fn info(self, context: impl Display) -> Result<T, E>

Log the context as an “info” if the Result is an Err.

fn debug(self, context: impl Display) -> Result<T, E>

Log the context as an “debug” if the Result is an Err.

fn trace(self, context: impl Display) -> Result<T, E>

Log the context as an “trace” if the Result is an Err.

fn with_error<F: FnOnce(&E) -> D, D: Display>(self, f: F) -> Result<T, E>

Lazily call [f] if the Result is an Err and log as an “error”.

fn with_warn<F: FnOnce(&E) -> D, D: Display>(self, f: F) -> Result<T, E>

Lazily call [f] if the Result is an Err and log as an “warn”.

fn with_info<F: FnOnce(&E) -> D, D: Display>(self, f: F) -> Result<T, E>

Lazily call [f] if the Result is an Err and log as an “info”.

fn with_debug<F: FnOnce(&E) -> D, D: Display>(self, f: F) -> Result<T, E>

Lazily call [f] if the Result is an Err and log as an “debug”.

fn with_trace<F: FnOnce(&E) -> D, D: Display>(self, f: F) -> Result<T, E>

Lazily call [f] if the Result is an Err and log as an “trace”.

fn consume_with_error<F: FnOnce(E) -> D, D: Display>(self, f: F) -> Option<T>

Consumes the Err of a Result. if Err, logging as an “error” with the result of [f].

fn consume_with_warn<F: FnOnce(E) -> D, D: Display>(self, f: F) -> Option<T>

Consumes the Err of a Result. if Err, logging as an “warn” with the result of [f].

fn consume_with_info<F: FnOnce(E) -> D, D: Display>(self, f: F) -> Option<T>

Consumes the Err of a Result. if Err, logging as an “info” with the result of [f].

fn consume_with_debug<F: FnOnce(E) -> D, D: Display>(self, f: F) -> Option<T>

Consumes the Err of a Result. if Err, logging as an “debug” with the result of [f].

fn consume_with_trace<F: FnOnce(E) -> D, D: Display>(self, f: F) -> Option<T>

Consumes the Err of a Result. if Err, logging as an “trace” with the result of [f].

Dyn Compatibility

This trait is not dyn compatible.

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