Enum EpollGetCapacityError 

pub enum EpollGetCapacityError {
    ProcFileDoesNotExist,
    ProcFileReadFailure,
    InsufficientPermissions,
    InsufficientMemory,
    PerProcessFileHandleLimitReached,
    SystemWideFileHandleLimitReached,
    Interrupt,
    InvalidProcFileContent,
    UnknownError,
}

Can be emitted by Epoll::capacity() when the epoll capacity is read from the proc file system.

Variants

ProcFileDoesNotExist

The proc file containing the capacity does not exist.

ProcFileReadFailure

The content of the proc file could not be read.

InsufficientPermissions

The process does not have the permission to open the proc file for reading.

InsufficientMemory

Insufficient memory to read from the proc file.

PerProcessFileHandleLimitReached

The process file handle limit has been reached.

SystemWideFileHandleLimitReached

The system wide file handle limit has been reached.

Interrupt

FetchableSignal::Interrupt was received (SIGINT).

InvalidProcFileContent

The proc file does not contain a number but something else.

UnknownError

An undocumented error occurred.

Trait Implementations

impl Clone for EpollGetCapacityError

fn clone(&self) -> EpollGetCapacityError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for EpollGetCapacityError

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

Formats the value using the given formatter.

impl Display for EpollGetCapacityError

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

Formats the value using the given formatter.

impl Error for EpollGetCapacityError

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 EpollGetCapacityError

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