Crate async_global_executor

A global executor built on top of async-executor and async_io

The global executor is lazily spawned on first use. It spawns as many threads as the number of cpus by default. You can override this using the ASYNC_GLOBAL_EXECUTOR_THREADS environment variable.

Examples

// spawn a task on the multi-threaded executor
let task1 = async_global_executor::spawn(async {
    1 + 2
});
// spawn a task on the local executor (same thread)
let task2 = async_global_executor::spawn_local(async {
    3 + 4
});
let task = future::zip(task1, task2);

// run the executor
async_global_executor::block_on(async {
    assert_eq!(task.await, (3, 7));
});

Structs

GlobalExecutorConfig

Configuration to init the thread pool for the multi-threaded global executor.

Task

A spawned task.

Functions

Runs the global and the local executor on the current thread

init

Init the global executor, spawning as many threads as the number or cpus or the value specified by the ASYNC_GLOBAL_EXECUTOR_THREADS environment variable if specified.

init_with_config

Init the global executor, spawning as many threads as specified or the value specified by the specified environment variable.

spawn

Spawns a task onto the multi-threaded global executor.

spawn_blocking

Runs blocking code on a thread pool.

spawn_local

Spawns a task onto the local executor.

spawn_more_threads

stop_thread
