rust-endianness

Library provides functions to read numbers from a stream of bytes either in big-endian or little-endian. Functions return Result type.

Usage

Read signed 16-bit integers:

```rust extern crate endianness; use endianness::*;

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

asserteq!(-32768, readi16(&v[0..2], ByteOrder::LittleEndian).unwrap()); asserteq!(-32768, readi16(&v[2..4], ByteOrder::BigEndian).unwrap()); ```

Read a signed 32-bit integer:

```rust 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:

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