Struct ErrnoCode 

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

Implementations

impl ErrnoCode

pub const fn from_return_value(retval: u64) -> Self

pub const fn from_error_code(code: i16) -> Self

pub const fn return_value(&self) -> u64

pub const fn error_code(&self) -> u32

pub fn is_restartable(&self) -> bool

Returns whether this ErrnoCode indicates that a restartable syscall was interrupted.

pub fn should_restart(&self, sigaction: Option<sigaction_t>) -> bool

Returns whether a combination of this ErrnoCode and a given sigaction_t mean that an interrupted syscall should be restarted.

Conditions for restarting syscalls:

• the error code is ERESTARTSYS, ERESTARTNOINTR, ERESTARTNOHAND, or ERESTART_RESTARTBLOCK and
• ERESTARTNOINTR is always restarted
• ERESTARTSYS is only restarted if the SA_RESTART flag is set in the sigaction_t
• all four error codes are restarted if no signal handler was present in the sigaction_t

Trait Implementations

impl Clone for ErrnoCode

fn clone(&self) -> ErrnoCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ErrnoCode

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

Formats the value using the given formatter.

impl Display for ErrnoCode

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

Formats the value using the given formatter.

impl PartialEq<ErrnoCode> for Errno

fn eq(&self, other: &ErrnoCode) -> 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.
