A zero-copy MAME ListInfo format DAT files parser and deserializer.

Usage

listinfo-rs provides a lower-level zero-copy expression tree API as well as a more user friendly Serde deserialization API.

Illustrated here is an example with the expression tree API

#[test]
fn parse_cave_story() {
const CAVE_STORY: &str = r#"clrmamepro (
name "Cave Story"
description "Cave Story"
version 20161204
comment "libretro | www.libretro.com"
)
game (
name "Cave Story (En)"
description "Cave Story (En)"
developer "Studio Pixel"
releaseyear "2004"
rom ( 
name "Doukutsu.exe"
size 1478656 
crc c5a2a3f6

let document = parse::parse_document(CAVE_STORY).unwrap();
let header = document.entry("clrmamepro").unwrap().next().unwrap();
let game = document.entry("game").unwrap().next().unwrap();
let rom = game.entry_unique("rom").unwrap();
assert_eq!(
header.entry_unique("name"),
Some(&EntryData::Scalar("Cave Story"))
);
assert_eq!(
game.entry_unique("name"),
Some(&EntryData::Scalar("Cave Story (En)"))
);
assert_eq!(
header.entry_unique("name"),
Some(&EntryData::Scalar("Cave Story"))
);
if let EntryData::SubEntry(rom) = rom {
assert_eq!(rom.value_unique("name"), Some("Doukutsu.exe"))
}
}

Features

listinfo-rs supports the following features

std Enables std support (enabled by default)
deserialize Enables support for serde deserialization

`no_std`

listinfo-rs requires alloc, but otherwise is fully supported on #![no_std] environments.

You can enable no_std support like in Cargo.toml

listinfo = { version = "0.3", default-features = false }
