Make marker searches utilize read buffer This turns the search into a near perfect opportunity for memchr which should be MUCH faster than calling the underlying reader's read method for each single byte we want to inspect.
A Rust library for decoding JPEGs.
Cargo.toml:
[dependencies] jpeg-decoder = "0.1"
main.rs:
extern crate jpeg_decoder as jpeg; use std::fs::File; use std::io::BufReader; fn main() { let file = File::open("hello_world.jpg").expect("failed to open file"); let mut decoder = jpeg::Decoder::new(BufReader::new(file)); let pixels = decoder.decode().expect("failed to decode image"); let metadata = decoder.info().unwrap(); }
This crate compiles only with rust >= 1.34.
