Variants (Non-exhaustive)

This enum is marked as non-exhaustive

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.
