[][src]Struct nix::sys::select::FdSet

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

Implementations

impl FdSet[src]

pub fn new() -> FdSet[src]

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

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

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

pub fn clear(&mut self)[src]

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

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));

pub fn fds(&mut self, highest: Option<RawFd>) -> Fds<'_>

Notable traits for Fds<'a>

impl<'a> Iterator for Fds<'a> type Item = RawFd;
[src]

Returns an iterator over the file descriptors in the set.

For performance, it takes an optional higher bound: the iterator will not return any elements of the set greater than the given file descriptor.

Examples

let mut set = FdSet::new();
set.insert(4);
set.insert(9);
let fds: Vec<RawFd> = set.fds(None).collect();
assert_eq!(fds, vec![4, 9]);
