//! # List of parsers and combinators
//!
//! <div class="warning">
//!
//! **Note**: this list is meant to provide a nicer way to find a parser than reading through the documentation on docs.rs. Function combinators are organized in module so they are a bit easier to find.
//!
//! </div>
//!
//! ## Basic elements
//!
//! Those are used to take a series of tokens for the lowest level elements of your grammar, like, "here is a dot", or "here is an big endian integer".
//!
//! | combinator | usage | input | new input | output | comment |
//! |---|---|---|---|---|---|
//! | [`one_of`][crate::token::one_of] | `one_of(['a', 'b', 'c'])` |  `"abc"` |  `"bc"` | `Ok('a')` |Matches one of the provided [set of tokens][crate::stream::ContainsToken] (works with non ASCII characters too)|
//! | [`none_of`][crate::token::none_of] | `none_of(['a', 'b', 'c'])` |  `"xyab"` |  `"yab"` | `Ok('x')` |Matches anything but one of the provided [set of tokens][crate::stream::ContainsToken]|
//! | [`literal`][crate::token::literal] | `"hello"` |  `"hello world"` |  `" world"` | `Ok("hello")` |Recognizes a specific suite of characters or bytes (see also [`Caseless`][crate::ascii::Caseless])|
//! | [`take`][crate::token::take] | `take(4)` |  `"hello"` |  `"o"` | `Ok("hell")` |Takes a specific number of bytes or characters|
//! | [`take_while`][crate::token::take_while] | `take_while(0.., is_alphabetic)` |  `"abc123"` |  `"123"` | `Ok("abc")` |Returns the longest slice of bytes or characters for which the provided [set of tokens][crate::stream::ContainsToken] matches.|
//! | [`take_till`][crate::token::take_till] | `take_till(0.., is_alphabetic)` |  `"123abc"` |  `"abc"` | `Ok("123")` |Returns a slice of bytes or characters until the provided [set of tokens][crate::stream::ContainsToken] matches. This is the reverse behaviour from `take_while`: `take_till(f)` is equivalent to `take_while(0.., \|c\| !f(c))`|
//! | [`take_until`][crate::token::take_until] | `take_until(0.., "world")` |  `"Hello world"` |  `"world"` | `Ok("Hello ")` |Returns a slice of bytes or characters until the provided [literal][crate::token::literal] is found.|
//!
//! ## Choice combinators
//!
//! | combinator | usage | input | new input | output | comment |
//! |---|---|---|---|---|---|
//! | [`alt`] | `alt(("ab", "cd"))` |  `"cdef"` |  `"ef"` | `Ok("cd")` |Try a list of parsers and return the result of the first successful one|
//! | [`dispatch`] | \- | \- | \- | \- | `match` for parsers |
//! | [`permutation`] | `permutation(("ab", "cd", "12"))` | `"cd12abc"` | `"c"` | `Ok(("ab", "cd", "12"))` |Succeeds when all its child parser have succeeded, whatever the order|
//!
//! ## Sequence combinators
//!
//! | combinator | usage | input | new input | output | comment |
//! |---|---|---|---|---|---|
//! | [`(...)` (tuples)][crate::Parser] | `("ab", "XY", take(1))` | `"abXYZ!"` | `"!"` | `Ok(("ab", "XY", "Z"))` |Parse a series of values|
//! | [`seq!`] | `seq!(_: '(', take(2), _: ')')` | `"(ab)cd"` | `"cd"` | `Ok("ab")` |Parse a series of values, discarding those you specify|
//! | [`delimited`] | `delimited('(', take(2), ')')` | `"(ab)cd"` | `"cd"` | `Ok("ab")` |Parse three values, discarding the first and third value|
//! | [`preceded`] | `preceded("ab", "XY")` | `"abXYZ"` | `"Z"` | `Ok("XY")` |Parse two values, discarding the first value|
//! | [`terminated`] | `terminated("ab", "XY")` | `"abXYZ"` | `"Z"` | `Ok("ab")` |Parse two values, discarding the second value|
//! | [`separated_pair`] | `separated_pair("hello", ',', "world")` | `"hello,world!"` | `"!"` | `Ok(("hello", "world"))` | Parse three values, discarding the middle value|
//!
//! ## Applying a parser multiple times
//!
//! | combinator | usage | input | new input | output | comment |
//! |---|---|---|---|---|---|
//! | [`repeat`] | `repeat(1..=3, "ab")` | `"ababc"` | `"c"` | `Ok(vec!["ab", "ab"])` |Applies the parser between m and n times (n included) and returns the list of results in a Vec|
//! | [`repeat_till`] | `repeat_till(0.., "ab", "ef")` | `"ababefg"` | `"g"` | `Ok((vec!["ab", "ab"], "ef"))` |Applies the first parser until the second applies. Returns a tuple containing the list of results from the first in a Vec and the result of the second|
//! | [`separated`] | `separated(1..=3, "ab", ",")` | `"ab,ab,ab."` | `"."` | `Ok(vec!["ab", "ab", "ab"])` |Applies the parser and separator between m and n times (n included) and returns the list of results in a Vec|
//! | [`Repeat::fold`] | <code>repeat(1..=2, `be_u8`).fold(\|\| 0, \|acc, item\| acc + item)</code> | `[1, 2, 3]` | `[3]` | `Ok(3)` |Applies the parser between m and n times (n included) and folds the list of return value|

//! ## Binary format parsing
//!
//! - [`length_repeat`][crate::binary::length_repeat] Gets a number from the first parser, then applies the second parser that many times
//! - [`length_take`][crate::binary::length_take]: Gets a number from the first parser, then takes a subslice of the input of that size, and returns that subslice
//! - [`length_and_then`][crate::binary::length_and_then]: Gets a number from the first parser, takes a subslice of the input of that size, then applies the second parser on that subslice. If the second parser returns `Incomplete`, `length_value` will return an error
//!
//! ### Integers
//!
//! Parsing integers from binary formats can be done in two ways: With parser functions, or combinators with configurable endianness.
//!
//! - **configurable endianness:** [`i16`][crate::binary::i16], [`i32`][crate::binary::i32],
//!   [`i64`][crate::binary::i64], [`u16`][crate::binary::u16], [`u32`][crate::binary::u32],
//!   [`u64`][crate::binary::u64] are combinators that take as argument a
//!   [`winnow::binary::Endianness`][crate::binary::Endianness], like this: `i16(endianness)`. If the
//!   parameter is `winnow::binary::Endianness::Big`, parse a big endian `i16` integer, otherwise a
//!   little endian `i16` integer.
//! - **fixed endianness**: The functions are prefixed by `be_` for big endian numbers, and by `le_` for little endian numbers, and the suffix is the type they parse to. As an example, `be_u32` parses a big endian unsigned integer stored in 32 bits.
//!   - [`be_f32`][crate::binary::be_f32], [`be_f64`][crate::binary::be_f64]: Big endian floating point numbers
//!   - [`le_f32`][crate::binary::le_f32], [`le_f64`][crate::binary::le_f64]: Little endian floating point numbers
//!   - [`be_i8`][crate::binary::be_i8], [`be_i16`][crate::binary::be_i16], [`be_i24`][crate::binary::be_i24], [`be_i32`][crate::binary::be_i32], [`be_i64`][crate::binary::be_i64], [`be_i128`][crate::binary::be_i128]: Big endian signed integers
//!   - [`be_u8`][crate::binary::be_u8], [`be_u16`][crate::binary::be_u16], [`be_u24`][crate::binary::be_u24], [`be_u32`][crate::binary::be_u32], [`be_u64`][crate::binary::be_u64], [`be_u128`][crate::binary::be_u128]: Big endian unsigned integers
//!   - [`le_i8`][crate::binary::le_i8], [`le_i16`][crate::binary::le_i16], [`le_i24`][crate::binary::le_i24], [`le_i32`][crate::binary::le_i32], [`le_i64`][crate::binary::le_i64], [`le_i128`][crate::binary::le_i128]: Little endian signed integers
//!   - [`le_u8`][crate::binary::le_u8], [`le_u16`][crate::binary::le_u16], [`le_u24`][crate::binary::le_u24], [`le_u32`][crate::binary::le_u32], [`le_u64`][crate::binary::le_u64], [`le_u128`][crate::binary::le_u128]: Little endian unsigned integers
//!
//! ### Bit stream parsing
//!
//! - [`bits`][crate::binary::bits::bits]: Transforms the current input type (byte slice `&[u8]`) to a bit stream on which bit specific parsers and more general combinators can be applied
//! - [`bytes`][crate::binary::bits::bytes]: Transforms its bits stream input back into a byte slice for the underlying parser
//! - [`take`][crate::binary::bits::take]: Take a set number of bits
//! - [`pattern`][crate::binary::bits::pattern]: Check if a set number of bits matches a pattern
//! - [`bool`][crate::binary::bits::bool]: Match any one bit
