Struct kernel::error::Error

pub struct Error(/* private fields */);

Generic integer kernel error.

The kernel defines a set of integer generic error codes based on C and POSIX ones. These codes may have a more specific meaning in some contexts.

Invariants

The value is a valid errno (i.e. >= -MAX_ERRNO && < 0).

Implementations

impl Error

pub fn to_errno(self) -> c_int

Returns the kernel error code.

pub fn name(&self) -> Option<&'static CStr>

Returns a string representing the error, if one exists.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Error

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

Formats the value using the given formatter.

impl From<AllocError> for Error

fn from(_: AllocError) -> Error

Converts to this type from the input type.

impl From<CStrConvertError> for Error

fn from(_: CStrConvertError) -> Error

Converts to this type from the input type.

impl From<Error> for Error

fn from(_: Error) -> Error

Converts to this type from the input type.

impl From<Infallible> for Error

fn from(e: Infallible) -> Error

Converts to this type from the input type.

impl From<LayoutError> for Error

fn from(_: LayoutError) -> Error

Converts to this type from the input type.

impl From<TryFromIntError> for Error

fn from(_: TryFromIntError) -> Error

Converts to this type from the input type.

impl From<TryReserveError> for Error

fn from(_: TryReserveError) -> Error

Converts to this type from the input type.

impl From<Utf8Error> for Error

fn from(_: Utf8Error) -> Error

Converts to this type from the input type.

impl PartialEq<Error> for Error

fn eq(&self, other: &Error) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
