Struct runa_io::OwnedFds

pub struct OwnedFds<const N: usize> { /* private fields */ }

Implementations

impl<const N: usize> OwnedFds<N>

pub fn new() -> Self

pub fn as_ptr(&self) -> *const OwnedFd

pub unsafe fn as_raw_fds(&self) -> &[RawFd]

Return a slice of raw file descriptors.

Safety

the caller must ensure to not close the file descriptors.

Trait Implementations

impl<const N: usize> Debug for OwnedFds<N>

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

Formats the value using the given formatter.

impl<const N: usize> Default for OwnedFds<N>

fn default() -> Self

Returns the “default value” for a type.

impl<const N: usize> Drop for OwnedFds<N>

fn drop(&mut self)

Executes the destructor for this type.

impl<const N: usize> Extend<OwnedFd> for OwnedFds<N>

fn extend<T: IntoIterator<Item = OwnedFd>>(&mut self, fds: T)

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<const N: usize> OwnedFds for OwnedFds<N>

fn len(&self) -> usize

Returns the number of file descriptors.

fn capacity(&self) -> Option<usize>

Returns the maximum number of file descriptors that can be stored. Trying to store more than this number of file descriptors will cause them to be dropped.

fn take<T: Extend<OwnedFd>>(&mut self, fds: &mut T)

Take all the file descriptors out of this object.

fn is_empty(&self) -> bool

Returns true if there are no file descriptors.
