Labeled Tab-separated Values (LTSV) format is a variant of Tab-separated Values (TSV). Each record in a LTSV file is represented as a single line. Each field is separated by TAB and has a label and a value. The label and the value have been separated by ':'. With the LTSV format, you can parse each line by spliting with TAB (like original TSV format) easily, and extend any fields with unique labels in no particular order.

Quickstart

You can start using it by first adding it to your Cargo.toml:

[dependencies]
serde_derive = "1.0"
serde_ltsv = "0.1"

Then, create a structure which implement serde::Serialize / serde::Deserialize traits and use the structure with any serde lib.

#[macro_use]
extern crate serde_derive;
extern crate serde_ltsv;
extern crate serde_json;
extern crate serde_yaml;

#[derive(Serialize, Deserialize)]
struct Foo {
    a: String,
    b: i8,
    c: bool
}

fn main() {
    let t = Foo { a: "toto".into(), b: 8, c: true };
    let str_t = serde_ltsv::to_string(&t).unwrap();
    println!("As ltsv => {}", &str_t);
    let t2: Foo = serde_ltsv::from_str(&str_t).unwrap();
    println!("As json => {}", serde_json::to_string_pretty(&t2).unwrap());
    println!("As yaml => {}", serde_yaml::to_string(&t2).unwrap());
}

Output:

As ltsv => a:toto	b:8	c:true
As json => {
    "a": "toto",
    "b": 8,
    "c": true
}
As yaml => ---
a: toto
b: 8
c: true
