//! A library that provides ASCII-only string and character types, equivalent to the `char`, `str`
//! and `String` types in the standard library.
//!
//! Please refer to the readme file to learn about the different feature modes of this crate.
//!
//! # Minimum supported Rust version
//!
//! The minimum Rust version for 1.1.\* releases is 1.41.1.
//! Later 1.y.0 releases might require newer Rust versions, but the three most
//! recent stable releases at the time of publishing will always be supported.  
//! For example this means that if the current stable Rust version is 1.70 when
//! ascii 1.2.0 is released, then ascii 1.2.\* will not require a newer
//! Rust version than 1.68.
//!
//! # History
//!
//! This package included the Ascii types that were removed from the Rust standard library by the
//! 2014-12 [reform of the `std::ascii` module](https://github.com/rust-lang/rfcs/pull/486). The
//! API changed significantly since then.

// Clippy lints
#![warn(
    clippy::pedantic,
    clippy::decimal_literal_representation,
    clippy::get_unwrap,
    clippy::indexing_slicing
)]
// Naming conventions sometimes go against this lint
#![allow(clippy::module_name_repetitions)]
// We need to get literal non-asciis for tests
#![allow(clippy::non_ascii_literal)]
// Sometimes it looks better to invert the order, such as when the `else` block is small
#![allow(clippy::if_not_else)]
// Shadowing is common and doesn't affect understanding
// TODO: Consider removing `shadow_unrelated`, as it can show some actual logic errors
#![allow(clippy::shadow_unrelated, clippy::shadow_reuse, clippy::shadow_same)]
// A `if let` / `else` sometimes looks better than using iterator adaptors
#![allow(clippy::option_if_let_else)]
// In tests, we're fine with indexing, since a panic is a failure.
#![cfg_attr(test, allow(clippy::indexing_slicing))]
// for compatibility with methods on char and u8
#![allow(clippy::trivially_copy_pass_by_ref)]
// In preparation for feature `unsafe_block_in_unsafe_fn` (https://github.com/rust-lang/rust/issues/71668)
