ArceOS task management module
Documentation
//! [ArceOS](https://github.com/arceos-org/arceos) task management module.
//!
//! This module provides primitives for task management, including task
//! creation, scheduling, sleeping, termination, etc. The scheduler algorithm
//! is configurable by cargo features.
//!
//! # Cargo Features
//!
//! - `multitask`: Enable multi-task support. If it's enabled, complex task
//!   management and scheduling is used, as well as more task-related APIs.
//!   Otherwise, only a few APIs with naive implementation is available.
//! - `irq`: Interrupts are enabled. If this feature is enabled, timer-based
//!   APIs can be used, such as [`sleep`], [`sleep_until`], and
//!   [`WaitQueue::wait_timeout`].
//! - `preempt`: Enable preemptive scheduling.
//! - `sched-fifo`: Use the [FIFO cooperative scheduler][1]. It also enables the
//!   `multitask` feature if it is enabled. This feature is enabled by default,
//!   and it can be overriden by other scheduler features.
//! - `sched-rr`: Use the [Round-robin preemptive scheduler][2]. It also enables
//!   the `multitask` and `preempt` features if it is enabled.
//! - `sched-cfs`: Use the [Completely Fair Scheduler][3]. It also enables the
//!   the `multitask` and `preempt` features if it is enabled.
