Struct nix::sys::select::FdSet

#[repr(C)]pub struct FdSet(_);

Implementations

impl FdSet

pub fn new() -> FdSet

pub fn insert(&mut self, fd: RawFd)

pub fn remove(&mut self, fd: RawFd)

pub fn contains(&mut self, fd: RawFd) -> bool

pub fn clear(&mut self)

pub fn highest(&mut self) -> Option<RawFd>

Finds the highest file descriptor in the set.

Returns None if the set is empty.

This can be used to calculate the nfds parameter of the select function.

Example

let mut set = FdSet::new();
set.insert(4);
set.insert(9);
assert_eq!(set.highest(), Some(9));
