Extension trait for Result which helps dealing with UEFI’s warnings

Required methods

fn status(&self) -> Status

Extract the UEFI status from this result

fn log_warning(self) -> Result<Output, Error<ErrData>>

Ignore warnings, keeping a trace of them in the logs

fn unwrap_success(self) -> Output

Expect success without warnings, panic otherwise

fn expect_success(self, msg: &str) -> Output

Expect success without warnings, panic with provided message otherwise

fn expect_error(self, msg: &str) -> Error<ErrData>

Expect error, panic with provided message otherwise, discarding output

fn map_inner<Mapped>(
    self,
    f: impl FnOnce(Output) -> Mapped
) -> Result<Mapped, ErrData>

Transform the inner output, if any

fn discard_errdata(self) -> Result<Output>

Transform the ErrData value to ()

fn warning_as_error(self) -> Result<Output, Error<ErrData>> where
    ErrData: Default, 

Treat warnings as errors
