Implementations

impl Edn

pub fn to_float(&self) -> Option<f64>

to_float takes an Edn and returns an Option<f64> with its value. Most types return None

use edn_rs::edn::{Edn, Vector};

let key = Edn::Key(String::from("1234"));
let q = Edn::Rational(String::from("3/4"));
let i = Edn::Int(12isize);

assert_eq!(Edn::Vector(Vector::empty()).to_float(), None);
assert_eq!(key.to_float().unwrap(),1234f64);
assert_eq!(q.to_float().unwrap(), 0.75f64);
assert_eq!(i.to_float().unwrap(), 12f64);

pub fn to_int(&self) -> Option<isize>

to_int takes an Edn and returns an Option<isize> with its value. Most types return None

use edn_rs::edn::{Edn, Vector};

let key = Edn::Key(String::from("1234"));
let q = Edn::Rational(String::from("3/4"));
let f = Edn::Double(12.3f64.into());

assert_eq!(Edn::Vector(Vector::empty()).to_float(), None);
assert_eq!(key.to_int().unwrap(),1234isize);
assert_eq!(q.to_int().unwrap(), 1isize);
assert_eq!(f.to_int().unwrap(), 12isize);

pub fn get<I: Index>(&self, index: I) -> Option<&Edn>

Index into a EDN vector, list, set or map. A string index can be used to access a value in a map, and a usize index can be used to access an element of a seqs.

Returns None if the type of self does not match the type of the index, for example if the index is a string and self is a seq or a number. Also returns None if the given key does not exist in the map or the given index is not within the bounds of the seq.

#[macro_use]
extern crate edn_rs;
use edn_rs::edn::{Edn, Map, Vector};

fn main() {
    let edn = edn!([ 1 1.2 3 {false :f nil 3/4}]);

    assert_eq!(edn[1], edn!(1.2));
    assert_eq!(edn.get(1).unwrap(), &edn!(1.2));
    assert_eq!(edn[3]["false"], edn!(:f));
    assert_eq!(edn[3].get("false").unwrap(), &Edn::Key("f".to_string()));
}

pub fn get_mut<I: Index>(&mut self, index: I) -> Option<&mut Edn>

Mutably index into a EDN vector, set, list or map. A string index can be used to access a value in a map, and a usize index can be used to access an element of a seq.

Returns None if the type of self does not match the type of the index, for example if the index is a string and self is a seq or a number. Also returns None if the given key does not exist in the map or the given index is not within the bounds of the seq.

#[macro_use]
extern crate edn_rs;
use edn_rs::edn::{Edn, Map, Vector};

fn main() {
    let mut edn = edn!([ 1 1.2 3 {false :f nil 3/4}]);

    assert_eq!(edn[1], edn!(1.2));
    assert_eq!(edn.get_mut(1).unwrap(), &edn!(1.2));
    assert_eq!(edn[3]["false"], edn!(:f));
    assert_eq!(edn[3].get_mut("false").unwrap(), &Edn::Key("f".to_string()));
}
