Struct miri::shims::unix::linux::epoll::Epoll

struct Epoll {
    file_descriptors: FxHashMap<i32, EpollEvent>,
}

An Epoll file descriptor connects file handles and epoll events

Fields

file_descriptors: FxHashMap<i32, EpollEvent>

The file descriptors we are watching, and what we are watching for.

Trait Implementations

impl Clone for Epoll

fn clone(&self) -> Epoll

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Epoll

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

Formats the value using the given formatter.

impl Default for Epoll

fn default() -> Epoll

Returns the “default value” for a type.

impl FileDescription for Epoll

fn name(&self) -> &'static str

fn close<'tcx>( self: Box<Self>, _communicate_allowed: bool ) -> InterpResult<'tcx, Result<()>>

fn read<'tcx>( &mut self, _communicate_allowed: bool, _bytes: &mut [u8], _tcx: TyCtxt<'tcx> ) -> InterpResult<'tcx, Result<usize>>

Reads as much as possible into the given buffer, and returns the number of bytes read.

fn write<'tcx>( &mut self, _communicate_allowed: bool, _bytes: &[u8], _tcx: TyCtxt<'tcx> ) -> InterpResult<'tcx, Result<usize>>

Writes as much as possible from the given buffer, and returns the number of bytes written.

fn seek<'tcx>( &mut self, _communicate_allowed: bool, _offset: SeekFrom ) -> InterpResult<'tcx, Result<u64>>

Seeks to the given offset (which can be relative to the beginning, end, or current position). Returns the new position from the start of the stream.

fn is_tty(&self, _communicate_allowed: bool) -> bool

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
