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

struct Epoll {
    interest_list: RefCell<BTreeMap<(FdId, i32), Rc<RefCell<EpollEventInterest>>>>,
    ready_list: Rc<RefCell<BTreeMap<(FdId, i32), EpollEventInstance>>>,
    thread_id: RefCell<Vec<ThreadId>>,
}

An Epoll file descriptor connects file handles and epoll events

Fields

interest_list: RefCell<BTreeMap<(FdId, i32), Rc<RefCell<EpollEventInterest>>>>

A map of EpollEventInterests registered under this epoll instance. Each entry is differentiated using FdId and file descriptor value.

ready_list: Rc<RefCell<BTreeMap<(FdId, i32), EpollEventInstance>>>

A map of EpollEventInstance that will be returned when epoll_wait is called. Similar to interest_list, the entry is also differentiated using FdId and file descriptor value.

thread_id: RefCell<Vec<ThreadId>>

A list of thread ids blocked on this epoll instance.

Implementations

impl Epoll

fn get_ready_list( &self, ) -> Rc<RefCell<BTreeMap<(FdId, i32), EpollEventInstance>>>

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, _ecx: &mut MiriInterpCx<'tcx>, ) -> InterpResult<'tcx, Result<()>>

fn read<'tcx>( &self, _self_ref: &FileDescriptionRef, _communicate_allowed: bool, _bytes: &mut [u8], _ecx: &mut MiriInterpCx<'tcx>, ) -> InterpResult<'tcx, Result<usize>>

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

fn write<'tcx>( &self, _self_ref: &FileDescriptionRef, _communicate_allowed: bool, _bytes: &[u8], _ecx: &mut MiriInterpCx<'tcx>, ) -> InterpResult<'tcx, Result<usize>>

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

fn pread<'tcx>( &self, _communicate_allowed: bool, _bytes: &mut [u8], _offset: u64, _ecx: &mut MiriInterpCx<'tcx>, ) -> InterpResult<'tcx, Result<usize>>

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

fn pwrite<'tcx>( &self, _communicate_allowed: bool, _bytes: &[u8], _offset: u64, _ecx: &mut MiriInterpCx<'tcx>, ) -> InterpResult<'tcx, Result<usize>>

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

fn seek<'tcx>( &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 flock<'tcx>( &self, _communicate_allowed: bool, _op: FlockOp, ) -> InterpResult<'tcx, Result<()>>

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

fn get_epoll_ready_events<'tcx>(&self) -> InterpResult<'tcx, EpollReadyEvents>

Check the readiness of file description.

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.
