std/async/mod.ts

The Deno Standard Library
Latest
The Standard Library has been moved to JSR. See the blog post for details.
import * as mod from "https://deno.land/std@0.224.0/async/mod.ts";

Provide help with asynchronous tasks like delays, debouncing, deferring, or pooling.

import { delay } from "https://deno.land/std@0.224.0/async/delay.ts";

await delay(100); // waits for 100 milliseconds

Classes

Error thrown when Deadline times out.

Multiplexes multiple async iterators into a single stream. It currently makes an assumption that the final result (the value returned and not yielded from the iterator) does not matter; if there is any result, it is discarded.

Error thrown in retry once the maximum number of failed attempts has been reached.

Variables

Error message emitted from the thrown error while mapping.

Functions

Make Promise abortable with the given signal.

Make AsyncIterable abortable with the given signal.

Make Promise abortable with the given signal.

Create a promise which will be rejected with DeadlineError when a given delay is exceeded.

Creates a debounced function that delays the given func by a given wait time in milliseconds. If the method is called again before the timeout expires, the previous call will be aborted.

Resolve a Promise after a given amount of milliseconds.

pooledMap transforms values from an (async) iterable into another async iterable. The transforms are done concurrently, with a max concurrency defined by the poolLimit.

Calls the given (possibly asynchronous) function up to maxAttempts times. Retries as long as the given function throws. If the attempts are exhausted, throws a RetryError with cause set to the inner exception.

Branches the given async iterable into the n branches.

Interfaces

Options for Deadline.

A debounced function that will be delayed by a given wait time in milliseconds. If the method is called again before the timeout expires, the previous call will be aborted.

Options for delay.

Options for retry.
