Implementations

impl Error

pub fn from_errno(errno: usize) -> Error

Convert a raw errno value into a typed Error.

pub fn to_errno(&self) -> usize

Convert this error to its numeric errno representation.

pub fn demux(ret: usize) -> Result<usize, Error>

Decode a raw syscall return value into Result.

pub fn is_retryable(&self) -> bool

Return true when retrying later may succeed (EINTR/EAGAIN).

pub fn name(&self) -> &'static str

Return the canonical symbolic errno name.

Trait Implementations

impl Clone for Error

fn clone(&self) -> Error

Returns a duplicate 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<(), Error>

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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.

impl PartialEq for Error

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl TryFrom<usize> for Error

type Error = TryFromPrimitiveError<Error>

The type returned in the event of a conversion error.

fn try_from(number: usize) -> Result<Error, TryFromPrimitiveError<Error>>

Performs the conversion.

impl TryFromPrimitive for Error

const NAME: &'static str = "Error"

type Primitive = usize

type Error = TryFromPrimitiveError<Error>

fn try_from_primitive( number: <Error as TryFromPrimitive>::Primitive, ) -> Result<Error, TryFromPrimitiveError<Error>>

impl Copy for Error

impl Eq for Error

impl StructuralPartialEq for Error
