Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl Errno

pub const EWOULDBLOCK: Errno = Errno::EAGAIN

pub const EDEADLOCK: Errno = Errno::EDEADLK

pub const ENOTSUP: Errno = Errno::EOPNOTSUPP

impl Errno

pub fn last() -> Self

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

pub const fn from_i32(err: i32) -> Errno

pub fn clear()

pub fn result<S: ErrnoSentinel + PartialEq<S>>(value: S) -> Result<S>

Returns Ok(value) if it does not contain the sentinel value. This should not be used when -1 is not the errno sentinel value.

Trait Implementations

impl Clone for Errno

fn clone(&self) -> Errno

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Errno

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

Formats the value using the given formatter.

impl Display for Errno

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

Formats the value using the given formatter.

impl Error for Errno

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 From<Errno> for Error

fn from(err: Errno) -> Self

Converts to this type from the input type.

impl PartialEq for Errno

fn eq(&self, other: &Errno) -> 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<Error> for Errno

type Error = Error

The type returned in the event of a conversion error.

fn try_from(ioerror: Error) -> Result<Self, Error>

Performs the conversion.

impl Copy for Errno

impl Eq for Errno

impl StructuralPartialEq for Errno
