Enum VarError

pub enum VarError {
    GetErr(Error<Option<usize>>),
    CastErr(PodCastError),
    StrErr(FromSliceWithNulError),
}

An Error that may result from attempting to get value from a UEFI variable.

Variants

GetErr(Error<Option<usize>>)

The variable could not be obtained.

CastErr(PodCastError)

The string variable could not be cast into a u16.

StrErr(FromSliceWithNulError)

The variable did not contain a string with valid characters or a nul terminator.

Trait Implementations

impl Debug for VarError

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

Formats the value using the given formatter.

impl Display for VarError

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

Formats the value using the given formatter.

impl Error for VarError

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.
