Crate lsdata

LSD (Less Syntax Data) configuration/data transfer format.

It is made out three variants - values (strings/words), lists ([]) and levels ({}). File may not contain only a value (it will be considered a level).

use lsdata::LSD;
use lsdata::LSDGetExt;
use lsdata::key;
use std::io::Cursor;

#[derive(Debug)]
enum CustomError {
    LanguageNameIsNotAValue,
    CouldNotFindLanguageName,
}

use CustomError::*;

let file = Cursor::new("languages.rust.name Rust");
let lsd = LSD::parse(file).unwrap();
let lang_key = "rust";
let lang_name = lsd
    .value(
        || LanguageNameIsNotAValue,
        key!["languages" lang_key "name"],
    )
    .unwrap()
    .ok_or_else(|| CouldNotFindLanguageName)
    .unwrap();
assert_eq!(lang_name, "Rust");
