Struct FdSet 

pub struct FdSet(/* private fields */);

File descriptor set for the virtual system

This is an implementation of the FdSet trait for the VirtualSystem. It represents a set of file descriptors that can be monitored for events such as readability or writability in the virtual system. Currently, the FdSet struct internally uses a BTreeSet to store the file descriptors, which allows for efficient insertion, removal, and lookup of file descriptors.

Implementations

impl FdSet

pub fn len(&self) -> usize

Returns the number of file descriptors in the set.

pub fn is_empty(&self) -> bool

Returns whether the set is empty.

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 duplicate 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() -> FdSet

Returns the “default value” for a type.

impl<'a> Extend<&'a Fd> for FdSet

fn extend<I: IntoIterator<Item = &'a Fd>>(&mut self, iter: I)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl Extend<Fd> for FdSet

fn extend<I: IntoIterator<Item = Fd>>(&mut self, iter: I)

Extends a collection with the contents of an iterator.

fn extend_one(&mut self, item: A)

🔬This is a nightly-only experimental API. (extend_one)

Extends a collection with exactly one element.

fn extend_reserve(&mut self, additional: usize)

🔬This is a nightly-only experimental API. (extend_one)

Reserves capacity in a collection for the given number of additional elements.

impl FdSet for FdSet

const MAX_FD: Fd

The maximum FD that can be stored in the set. This corresponds to FD_SETSIZE - 1 in C libraries. The exact value may depend on the implementation.

fn insert(&mut self, fd: Fd)

Adds an FD to the set.

fn remove(&mut self, fd: Fd)

Removes an FD from the set.

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

Checks if an FD is in the set.

fn new() -> Self

Creates a new, empty FD set.

fn from_fds<I>(iter: I) -> Self

where I: IntoIterator<Item = Fd>,

Creates a new FD set from an iterator of FDs.

impl From<Fd> for FdSet

fn from(fd: Fd) -> Self

Converts to this type from the input type.

impl FromIterator<Fd> for FdSet

fn from_iter<I: IntoIterator<Item = Fd>>(iter: I) -> Self

Creates a value from an iterator.

impl<'a> IntoIterator for &'a FdSet

type Item = &'a 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) -> Self::IntoIter

Creates an iterator from a value.

impl IntoIterator for FdSet

type Item = Fd

The type of the elements being iterated over.

type IntoIter = IntoIter

Which kind of iterator are we turning this into?

fn into_iter(self) -> Self::IntoIter

Creates an iterator from a value.

impl PartialEq for FdSet

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

Tests for self and other values to be equal, and is used by ==.

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

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