edn-rs

[Experimental] Crate to parse and emit EDN

Usage

Cargo.toml

[dependencies]
edn-rs = "0.2.1"

Parse an EDN into a EdnNode:

extern crate edn_rs;

use edn_rs::parse_edn;

fn main() {
    ...
    let edn = String::from("[1 2 [:3 \"4\"]]");
    let value = parse_edn(edn);
    ...
}

Emits EDN format from a Json file

use edn_rs::emit_edn;

fn main() {
    let json = String::from("{\"hello\": \"world\"}");
    let edn = String::from("{:hello \"world\"}");

    assert_eq!(edn, emit_edn(json));
}

Current Features

• Define struct to map EDN info EdnNode
• Define EDN types, EdnType
• Parse simples EDN data:
  • nil ""
  • String "\"string\""
  • Numbers "324352", "3442.234", "3/4"
  • Keywords
  • Vector "[1 :2 \"d\"]"
  • List "(1 :2 \"d\")"
  • Set "#{1 2 3}"
  • Map "{:a 1 :b 2 }"
  • Unbalanced Map returns EdnType::Err, "{:a 1 :b}"
• Simple data structures in one another:
  • Vec in Vec "[1 2 [:3 \"4\"]]"
  • Set in Vec "[1 2 #{:3 \"4\"}]"
  • List in List
  • Set in List
  • Set in Set (Sets will not be sorted and don't need a dedup due to the fact that they need to be compliant with EDN spec)
  • List in Set
  • Maps in general
• Multiple simple data structures in one another (Map and Set in a vector)
• Multi deepen data structures (Map in a Set in a List in a Vec in a Vec)
• Json to Edn
  • Json String to EDN String
  • macro to process Structs and Enums to EDN
• Edn to Json
