Crate tokio_with_wasm

A library that adapts the popular async runtime tokio for web browsers.

It provides a similar set of features specifically for web applications by leveraging the JavaScript web API.

This library includes JavaScript glue code to mimic the behavior of real tokio, making it possible to run asynchronous Rust code in the browser. Since tokio_with_wasm adapts to the JavaScript event loop and does not include its own runtime, some advanced features of tokio might not be fully supported.

Re-exports

pub use crate as alias;

Modules

sync

Synchronization primitives for use in asynchronous contexts.

task

Asynchronous green-threads.

time

Utilities for tracking time.

Macros

join

Waits on multiple concurrent branches, returning when all branches complete.

pin

Pins a value on the stack.

select

Waits on multiple concurrent branches, returning when the first branch completes, cancelling the remaining branches.

try_join

Waits on multiple concurrent branches, returning when all branches complete with Ok(_) or on the first Err(_).

Functions

spawn

Spawns a new asynchronous task, returning a JoinHandle for it.

Attribute Macros

main

Attribute macro that mimics tokio::main. This macro returns a function that simply spawns the given future inside the JavaScript environment. To execute the function, you might need to use #[wasm_bindgen(start)] in addition to this macro.
