    New blog post: Byte ordered stream parsing. Came up with a small set of API additions to the Read/Write traits to perform endian-aware reading and writing of numbers. https://yoshuawuyts-blog.netlify.com/byte-ordered-stream-parsing/ … (currently in the middle of a DNS migration, so a different domain than usual)pic.twitter.com/f2ofzxenTT

    let mut file = File::open("foo.txt")?;

// Write an i32 as little-endian.
file.write_le(56_i32)?;

// Read a u16 as big-endian.
let n: u16 = file.read_be()?;

        Cool, looks like my DNS finally rolled over and my blog is enabled again on my regular domain. Post now lives here:https://blog.yoshuawuyts.com/byte-ordered-stream-parsing/ …

        A bit late to this party but have you looked at scroll at all? I love it for parsing binary formats, especially when the task is "parse the format as defined by these C structs". With its proc macro derive it's really wonderful in practice: https://docs.rs/scroll/0.10.1/scroll/ …

        In this example you used the name "buf" in the declaration but "file" in the usage, also you need to borrow the .to_le_bytes() as it returns a [u8; 2] not an &[u8] (I only caught this because I've been writing a lot of code doing the exact same thing recently :P)pic.twitter.com/ryk8IaOCV9

        Which, to add, I personally have wanted something like this in the stdlib since the day I started rust, definitely a worthwhile addition.
