Struct yash_env::system::fd_set::FdSet

pub struct FdSet { /* private fields */ }

Set of file descriptors

Implementations

impl FdSet

pub fn new() -> Self

Creates a new empty set.

pub fn insert(&mut self, fd: Fd) -> Result<(), InvalidFd>

Inserts a file descriptor into the set.

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

Removes a file descriptor from the set.

pub fn clear(&mut self)

Removes all file descriptors from the set.

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

Returns true if the set contains the file descriptor.

pub fn upper_bound(&self) -> Fd

Returns some file descriptor that is larger than any file descriptor in the set.

pub fn iter(&self) -> Iter<'_>

Returns an iterator over the file descriptors in the set.

Trait Implementations

impl Clone for FdSet

fn clone(&self) -> FdSet

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for FdSet

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

Formats the value using the given formatter.

impl Default for FdSet

fn default() -> Self

Returns the “default value” for a type.

impl Hash for FdSet

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> IntoIterator for &'a FdSet

type Item = Fd

The type of the elements being iterated over.

type IntoIter = Iter<'a>

Which kind of iterator are we turning this into?

fn into_iter(self) -> Iter<'a>

Creates an iterator from a value.

impl PartialEq for FdSet

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
