    PerProcessFileHandleLimitReached,
    SystemWideFileHandleLimitReached,
    InsufficientMemory,
    UnableToMountInodeDevice,
    UnknownError(i32),
}

Error emitted when creating a new SignalFd.

Variants

PerProcessFileHandleLimitReached

The process wide file handle limit is reached

SystemWideFileHandleLimitReached

The system wide file handle limit is reached

InsufficientMemory

Insufficient memory available

UnableToMountInodeDevice

The underlying inode device could not be mounted

UnknownError(i32)

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

Trait Implementations

impl Clone for SignalFdCreationError

fn clone(&self) -> SignalFdCreationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignalFdCreationError

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

Formats the value using the given formatter.

impl Display for SignalFdCreationError

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

Formats the value using the given formatter.

impl Error for SignalFdCreationError

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 SignalFdCreationError

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 SignalFdCreationError

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