Crate endianness

This crate provides functions to read numbers from a stream of bytes either in big-endian or little-endian. Functions return Result type instead of panic!.

Examples

Read signed 16-bit integers:

let v = vec![0, 128, 128, 0];

assert_eq!(-32768, read_i16(&v[0..2], ByteOrder::LittleEndian).unwrap());
assert_eq!(-32768, read_i16(&v[2..4], ByteOrder::BigEndian).unwrap());

Read a signed 32-bit integer:

let v = vec![0, 128, 128, 0];

match read_i32(&v, ByteOrder::LittleEndian) {
    Ok(n) => println!("Read value {}", n), // 8421376
    Err(err) => println!("Error: {}", err),
}

Read a single-precision floating point number:

let v = vec![194, 255, 0, 0];
assert_eq!(-127.5, read_f32(&v[0..4], ByteOrder::BigEndian).unwrap());

Enums

ByteOrder	The 'ByteOrder' type. It represents the order of bytes in a stream we read from.
EndiannessError	The error type.

Functions

read_f32	Reads a single-precision floating point number.
read_f64	Reads a double-precision floating point number.
read_i16	Reads signed 16-bit integer from a stream of bytes.
read_i32	Reads signed 32-bit integer from a stream of bytes.
read_i64	Reads signed 64-bit integer from a stream of bytes.
read_u16	Reads unsigned 16-bit integer from a stream of bytes.
read_u32	Reads unsigned 32-bit integer from a stream of bytes.
read_u64	Reads unsigned 64-bit integer from a stream of bytes.
