//! Task creation

//! An executing Rust program consists of a collection of tasks, each

//! backed by an operating system thread, making tasks 'just threads',

//! scheduling crate for creating tasks backed by green threads).

//! the main task panics the application will exit with a non-zero

//!
//! # Basic task scheduling
//!
//! By default, every task is created with the same "flavor" as the calling task.
//! This flavor refers to the scheduling mode, with two possibilities currently
//! being 1:1 and M:N modes. Green (M:N) tasks are cooperatively scheduled and
//! native (1:1) tasks are scheduled by the OS kernel.

//!
//! # Advanced task scheduling
//!
//! Task spawning can also be configured to use a particular scheduler, to
//! redirect the new task's output, or to yield a `future` representing the
//! task's final result. The configuration is established using the
//! `TaskBuilder` API:
//!
//! ## Example
//!
//! ```rust
//! extern crate green;
//! extern crate native;
//!
//! use std::task::TaskBuilder;
//! use green::{SchedPool, PoolConfig, GreenTaskBuilder};
//! use native::NativeTaskBuilder;
//!
//! # fn main() {
//! // Create a green scheduler pool with the default configuration
//! let mut pool = SchedPool::new(PoolConfig::new());
//!
//! // Spawn a task in the green pool
//! let mut fut_green = TaskBuilder::new().green(&mut pool).try_future(proc() {
//! /* ... */
//! });
//!
//! // Spawn a native task
//! let mut fut_native = TaskBuilder::new().native().try_future(proc() {
//! /* ... */
//! });
//!
//! // Wait for both tasks to finish, recording their outcome
//! let res_green = fut_green.unwrap();
//! let res_native = fut_native.unwrap();

//! // Shut down the green scheduler pool
