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.
