Struct Builder 

pub struct Builder { /* private fields */ }

Customized channel construction.

Implementations

impl Builder

pub fn new() -> Self

Defaults to unbounded.

pub fn bounded(&mut self, capacity: usize) -> &mut Self

Define this channel as bounded with the given capacity.

Because handles can be converted freely between sync and async, and Rust async is polling, unbuffered channels are not supported. A capacity of 0 is rounded up to 1.

pub fn preallocate(&mut self) -> &mut Self

Preallocate bounded channels with their full capacity. This avoids reallocation at runtime.

Has no effect on unbounded channels.

pub fn build_async<T>(&mut self) -> (Sender<T>, Receiver<T>)

Allocates a channel and returns async sender and receiver handles.

pub fn build_sync<T>(&mut self) -> (SyncSender<T>, SyncReceiver<T>)

Allocates a channel and returns the synchronous sender and receiver handles.

Trait Implementations

impl Debug for Builder

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

Formats the value using the given formatter.

impl Default for Builder

fn default() -> Builder

Returns the “default value” for a type.
