buffer_io 1.0.0

This crate provides convenience methods for reading and writing data to binary buffers. It supports writing primitive types, as well as Strings and Vectors to in-memory streams and files.

Installation

This crate works with Cargo and is on crates.io. Add it to your Cargo.toml like so:

[dependencies]
buffer_io = "1"

If you want to write data to a buffer you do it like so:

use crate::buffer::{BufferReader, BufferWriter, SeekOrigin};
use std::io::Cursor;
let mut buffer = BufferWriter::new(Cursor::new(Vec::new()));
buffer.write_u32(9001)?;
buffer.write_u32(9002).unwrap()?;
buffer.write_string("Hello World!")?;

You can then return the full buffer as a vector:

let data = buffer.to_vec()?;

Reading buffers is just as simple.

let mut reader = BufferReader::new(File::open("test.bin")?);
let magic = reader.read_u32()?;
let body = reader.read_string()?;
