Enum EpollCreateError 

pub enum EpollCreateError {
    PerProcessFileHandleLimitReached,
    SystemWideFileHandleLimitReached,
    InsufficientMemory,
    SysCallReturnedInvalidFileDescriptor,
    UnableToEnableSignalHandling,
    UnknownError(i32),
}

Errors that can occur when EpollBuilder::create() creates a new Epoll.

Variants

PerProcessFileHandleLimitReached

The process file handle limit has been reached.

SystemWideFileHandleLimitReached

The system wide file handle limit has been reached.

InsufficientMemory

The system has not enough memory to create the Epoll

SysCallReturnedInvalidFileDescriptor

The syscall linux::epoll_create() returned a broken FileDescriptor.

UnableToEnableSignalHandling

EpollBuilder was configured to handle some FetchableSignals but the underlying SignalFd could not be created.

UnknownError(i32)

An error occurred that was not described in the linux man-page.

Trait Implementations

impl Clone for EpollCreateError

fn clone(&self) -> EpollCreateError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpollCreateError

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

Formats the value using the given formatter.

impl Display for EpollCreateError

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

Formats the value using the given formatter.

impl Error for EpollCreateError

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 PartialEq for EpollCreateError

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