This is a tokenizer for serialized Sixel images, for more info on the protocol, see: https://vt100.net/docs/vt3xx-gp/chapter14.html
Parser should be given sixel bytes one by one and a callback. The callback is called with a
SixelEvent zero or more times per byte when relevant.
```rust use sixel_tokenizer::Parser;
fn main() { let sample = " \u{1b}Pq \"2;1;100;200 #0;2;0;0;0#1;2;100;100;0#2;2;0;100;0 #1~~@@vv@@~~@@~~$ #2??}}GG}}??}}??- #1!14@ \u{1b}\ "; let samplebytes = sample.asbytes(); let mut events = vec![]; let mut parser = Parser::new(); for byte in samplebytes { parser.advance(&byte, |sixelevent| events.push(sixelevent)); } let mut snapshot = String::new(); for event in events { snapshot.pushstr(&format!("{:?}", event)); snapshot.push('\n'); } println!("{}", snapshot); } ```
This program will print:
