Expand description

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:

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());

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
