Struct WaitGroup 

pub struct WaitGroup { /* private fields */ }

A synchronization primitive for waiting on multiple tasks to complete.

See the module level documentation for more.

Implementations

impl WaitGroup

pub fn new() -> Self

Creates a new WaitGroup.

Examples

use mea::waitgroup::WaitGroup;

let wg = WaitGroup::new();

Trait Implementations

impl Clone for WaitGroup

fn clone(&self) -> Self

Creates a new worker handle for the WaitGroup.

This increments the WaitGroup counter. The counter will be decremented when the new handle is dropped.

Panics

Panics if the WaitGroup counter would overflow.

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

Performs copy-assignment from source.

impl Debug for WaitGroup

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

Formats the value using the given formatter.

impl Default for WaitGroup

fn default() -> Self

Returns the “default value” for a type.

impl Drop for WaitGroup

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

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

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.

impl IntoFuture for WaitGroup

fn into_future(self) -> Self::IntoFuture

Converts the WaitGroup into a future that completes when all tasks finish. This decreases the WaitGroup counter.

type Output = ()

The output that the future will produce on completion.

type IntoFuture = Wait

Which kind of future are we turning this into?
