Crate mco

A library for programming stackful coroutines in Rust.

mco is a high-performant library for programming stackful coroutines with which you can easily develop and maintain massive concurrent programs. It can be thought as the Rust version of the popular Goroutine.

Features

• The stackful coroutine’s implementation is based on generator;
• Support schedule on a configurable number of threads for multi-core systems;
• Support coroutine’s version of a local storage ([CLS][cls]);
• Support efficient asynchronous network I/O;
• Support efficient timer management;
• Support standard synchronization primitives, a semaphore, an MPMC channel, etc;
• Support cancellation of coroutines;
• Support graceful panic handling that will not affect other coroutines;
• Support scoped coroutine creation;
• Support general selection for all the coroutine’s API;
• All the coroutine’s API are compatible with the standard library semantics;
• All the coroutine’s API can be safely called in multi-threaded context;
• Both stable, beta, and nightly channels are supported;
• Both x86_64 GNU/Linux, x86_64 Windows, x86_64 Mac OS are supported.

Macros

chan

create an channel(mpmc) for example:

co

macro used to spawn a coroutine

coroutine_local

A macro to create a static of type LocalKey

cqueue_add

macro used to create the select coroutine that will run in a infinite loop, and generate as many events as possible

cqueue_add_oneshot

macro used to create the select coroutine that will run only once, thus generate only one event use mco::select;

defer

Defers evaluation of a block of code until the end of the scope. Sort of LIFO(last-in, first-out queue) If you encounter references to resources that cannot mut more than 2 times, try nesting RefCell and then use.borrow() and.borrow_mut().

err

mco::std::errors::Error

join

macro used to join all scoped sub coroutines for example:

select

macro used to select for only one event it will return the index of which event happens first for example:

select_token

macro used to select for only one event it will return the index of which event happens first for example:

spawn

macro used to spawn a coroutine

spawn_blocking

will spawn a thread to doing and return value by channel for example:

spawn_with

macro used to spawn a coroutine with options such as name, stack_size.

Structs

Config

mco Configuration type

LocalKey

A key for local data stored in a coroutine.

Functions

config

get the may configuration instance
