Trait HandlerResultExt 

pub trait HandlerResultExt<T> {
    // Required methods
    fn benign_err(self) -> Result<T, HandlerError>;
    fn recoverable_err(self) -> Result<T, HandlerError>;
    fn unrecoverable_err(self) -> Result<T, HandlerError>;
}

Extension helpers for classifying fallible results in component handlers.

These methods keep error classification local to the handler call site while still allowing convenient use of the ? operator.

Example

fn handler() -> HandlerResult {
    lookup().recoverable_err()?;
    Handled::OK
}

Required Methods

fn benign_err(self) -> Result<T, HandlerError>

Classify an Err value as HandlerError::Benign.

fn recoverable_err(self) -> Result<T, HandlerError>

Classify an Err value as HandlerError::Recoverable.

fn unrecoverable_err(self) -> Result<T, HandlerError>

Classify an Err value as HandlerError::Unrecoverable.
