Struct DescriptorTable

source
pub struct DescriptorTable { /* private fields */ }
Expand description

Map of file handles to file descriptors. Typically owned by a Thread.

Implementations§

source§

impl DescriptorTable

source

pub fn new() -> Self

source

pub fn get(&self, idx: DescriptorHandle) -> Option<&Descriptor>

Get the descriptor at idx, if any.

source

pub fn get_mut(&mut self, idx: DescriptorHandle) -> Option<&mut Descriptor>

Get the descriptor at idx, if any.

source

pub fn register_descriptor( &mut self, desc: Descriptor, ) -> Result<DescriptorHandle, Descriptor>

Register a descriptor and return its fd handle. Equivalent to register_descriptor_with_min_fd(desc, 0). If the descriptor could not be added, the descriptor is returned in the Err.

source

pub fn register_descriptor_with_min_fd( &mut self, desc: Descriptor, min_fd: DescriptorHandle, ) -> Result<DescriptorHandle, Descriptor>

Register a descriptor and return its fd handle. If the descriptor could not be added, the descriptor is returned in the Err.

source

pub fn register_descriptor_with_fd( &mut self, desc: Descriptor, new_fd: DescriptorHandle, ) -> Option<Descriptor>

Register a descriptor with a given fd handle and return the descriptor that it replaced.

source

pub fn deregister_descriptor( &mut self, fd: DescriptorHandle, ) -> Option<Descriptor>

Deregister the descriptor with the given fd handle and return it.

source

pub fn remove_all(&mut self) -> impl Iterator<Item = Descriptor>

Remove and return all descriptors.

source

pub fn remove_range( &mut self, range: impl RangeBounds<DescriptorHandle>, ) -> impl Iterator<Item = Descriptor>

Remove and return all descriptors in the range. If you want to remove all descriptors, you should use remove_all.

source

pub fn iter(&self) -> impl Iterator<Item = (&DescriptorHandle, &Descriptor)>

source

pub fn iter_mut( &mut self, ) -> impl Iterator<Item = (&DescriptorHandle, &mut Descriptor)>
