Enum SignalFdReadError 

pub enum SignalFdReadError {
    SystemBreaksReadContract,
    Interrupt,
    IOerror,
    InsufficientResources,
    InsufficientMemory,
    UnknownError(i32),
}

Error emitted from BlockingSignalFd::blocking_read() or SignalFd::try_read().

Variants

SystemBreaksReadContract

The amount of bytes read were less than the size of the internal siginfo struct

Interrupt

An interrupt signal was raised

IOerror

An input/output error occurred

InsufficientResources

Insufficient resources available

InsufficientMemory

Insufficient memory available

UnknownError(i32)

An error that was not documented in the POSIX API was reported

Trait Implementations

impl Clone for SignalFdReadError

fn clone(&self) -> SignalFdReadError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignalFdReadError

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

Formats the value using the given formatter.

impl Display for SignalFdReadError

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

Formats the value using the given formatter.

impl Error for SignalFdReadError

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 Hash for SignalFdReadError

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for SignalFdReadError

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