-/// Extends [`Read`] with methods for reading numbers. (For `std::io`.)
-///
-/// Most of the methods defined here have an unconstrained type parameter that
-/// must be explicitly instantiated. Typically, it is instantiated with either
-/// the [`BigEndian`] or [`LittleEndian`] types defined in this crate.
-///
-/// # Examples
-///
-/// Read unsigned 16 bit big-endian integers from a [`Read`]:
-///
-/// ```rust
-/// use std::io::Cursor;
-/// use byteorder::{BigEndian, ReadBytesExt};
-///
-/// let mut rdr = Cursor::new(vec![2, 5, 3, 0]);
-/// assert_eq!(517, rdr.read_u16::<BigEndian>().unwrap());
-/// assert_eq!(768, rdr.read_u16::<BigEndian>().unwrap());
-/// ```

-/// Most of the methods defined here have an unconstrained type parameter that

-/// # Examples

-/// Write unsigned 16 bit big-endian integers to a [`Write`]:
-///
-/// ```rust
-/// use byteorder::{BigEndian, WriteBytesExt};
-///
-/// let mut wtr = vec![];

-/// wtr.write_u16::<BigEndian>(768).unwrap();

-/*!
-This crate provides convenience methods for encoding and decoding numbers in
-either [big-endian or little-endian order].
-
-The organization of the crate is pretty simple. A trait, [`ByteOrder`], specifies
-byte conversion methods for each type of number in Rust (sans numbers that have
-a platform dependent size like `usize` and `isize`). Two types, [`BigEndian`]
-and [`LittleEndian`] implement these methods. Finally, [`ReadBytesExt`] and
-[`WriteBytesExt`] provide convenience methods available to all types that
-implement [`Read`] and [`Write`].
-
-An alias, [`NetworkEndian`], for [`BigEndian`] is provided to help improve
-code clarity.
-
-An additional alias, [`NativeEndian`], is provided for the endianness of the
-local platform. This is convenient when serializing data for use and
-conversions are not desired.
-
-# Examples
-
-Read unsigned 16 bit big-endian integers from a [`Read`] type:
-
-```rust
-use std::io::Cursor;
-use byteorder::{BigEndian, ReadBytesExt};
-
-let mut rdr = Cursor::new(vec![2, 5, 3, 0]);
-// Note that we use type parameters to indicate which kind of byte order
-// we want!
-assert_eq!(517, rdr.read_u16::<BigEndian>().unwrap());
-assert_eq!(768, rdr.read_u16::<BigEndian>().unwrap());
-```
-
-Write unsigned 16 bit little-endian integers to a [`Write`] type:
-
-```rust
-use byteorder::{LittleEndian, WriteBytesExt};
-
-let mut wtr = vec![];
-wtr.write_u16::<LittleEndian>(517).unwrap();
-wtr.write_u16::<LittleEndian>(768).unwrap();
-assert_eq!(wtr, vec![5, 2, 0, 3]);
-```
-
-# Optional Features
-
-This crate optionally provides support for 128 bit values (`i128` and `u128`)
-when built with the `i128` feature enabled.
-
-This crate can also be used without the standard library.
-
-# Alternatives
-
-Note that as of Rust 1.32, the standard numeric types provide built-in methods
-like `to_le_bytes` and `from_le_bytes`, which support some of the same use
-cases.
