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

fn name(&self) -> &'static str
fn close<'tcx>( self: Box<Self>, _communicate_allowed: bool ) -> InterpResult<'tcx, Result<()>>
source§fn read<'tcx>(
&mut self,
_communicate_allowed: bool,
_bytes: &mut [u8],
_tcx: TyCtxt<'tcx>
) -> InterpResult<'tcx, Result<usize>>
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.
source§fn write<'tcx>(
&mut self,
_communicate_allowed: bool,
_bytes: &[u8],
_tcx: TyCtxt<'tcx>
) -> InterpResult<'tcx, Result<usize>>
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.
source§fn seek<'tcx>(
&mut self,
_communicate_allowed: bool,
_offset: SeekFrom
) -> InterpResult<'tcx, Result<u64>>
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.

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.
