Struct NvramResult

pub struct NvramResult<T>(pub T, pub EfiStatus, pub Option<NvramError>);

Unlike a typical result type, NvramErrors contain both a payload and an error code. Depending on the error code, an optional NvramError might be included as well, which provides more context.

Notably, this result types cannot be propagated via the ? operator!

Trait Implementations

impl<T: Debug> Debug for NvramResult<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Display for NvramResult<T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T> Error for NvramResult<T>

where T: Debug,

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0: use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0: replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
