//! This tiny crate checks that the running or installed `rustc` meets some
//! version requirements. The version is queried by calling the Rust compiler
//! with `--version`. The path to the compiler is determined first via the
//! `RUSTC` environment variable. If it is not set, then `rustc` is used. If
//! that fails, no determination is made, and calls return `None`.
//!
//! # Examples
//!
//! * Set a `cfg` flag in `build.rs` if the running compiler was determined to
//! be at least version `1.13.0`:
//!
//! ```rust
//! extern crate version_check as rustc;
//!
//! if rustc::is_min_version("1.13.0").unwrap_or(false) {
//! println!("cargo:rustc-cfg=question_mark_operator");
//! }
//! ```
//!
//! See [`is_max_version`] or [`is_exact_version`] to check if the compiler
//! is _at most_ or _exactly_ a certain version.
//!
//! * Check that the running compiler was released on or after `2018-12-18`:
//!
//! ```rust
//! extern crate version_check as rustc;
//!
//! match rustc::is_min_date("2018-12-18") {
//! Some(true) => "Yep! It's recent!",
//! Some(false) => "No, it's older.",
//! None => "Couldn't determine the rustc version."
//! };
//! ```
//!
//! See [`is_max_date`] or [`is_exact_date`] to check if the compiler was
//! released _prior to_ or _exactly on_ a certain date.
//!
//! * Check that the running compiler supports feature flags:
//!
//! ```rust
//! extern crate version_check as rustc;
//!
//! match rustc::is_feature_flaggable() {
//! Some(true) => "Yes! It's a dev or nightly release!",
//! Some(false) => "No, it's stable or beta.",
//! None => "Couldn't determine the rustc version."
//! };
//! ```
//!
//! * Check that the running compiler supports a specific feature:
//!
//! ```rust
//! extern crate version_check as rustc;
//!
//! if let Some(true) = rustc::supports_feature("doc_cfg") {
//! println!("cargo:rustc-cfg=has_doc_cfg");
//! }
//! ```
//!
//! * Check that the running compiler is on the stable channel:
//!
//! ```rust
//! extern crate version_check as rustc;
//!
//! match rustc::Channel::read() {
//! Some(c) if c.is_stable() => format!("Yes! It's stable."),
//! Some(c) => format!("No, the channel {} is not stable.", c),
//! None => format!("Couldn't determine the rustc version.")
//! };
//! ```
//!
//! To interact with the version, release date, and release channel as structs,
//! use [`Version`], [`Date`], and [`Channel`], respectively. The [`triple()`]
//! function returns all three values efficiently.
//!
//! # Alternatives
//!
//! This crate is dead simple with no dependencies. If you need something more
//! and don't care about panicking if the version cannot be obtained, or if you
//! don't mind adding dependencies, see
//! [rustc_version](https://crates.io/crates/rustc_version).
