A pure-Rust crate to parse EDID data with no_std support. This crate does not include methods for gathering the data from the monitor.
To enable no_std support, ensure the alloc crate is available, use feature no_std, and then implement edid_rs::Read instead of std::io::Read for data sources.
Dual licensed under MIT and Apache-2.0.
Basic usage:
extern crate edid_rs;
use std::io::Cursor;
fn main() {
let bytes = vec![...];
println!("{:?}",
edid_rs::parse(&mut Cursor::new(bytes))
);
}Reading current monitor EDID on OSX:
$ ioreg -l -w0 -d0 -r -c AppleBacklightDisplay | grep IODisplayEDID - | tail -c 258 | head -c 256 | xxd -r -p | cargo run --example stdin
