Struct Obj 

pub struct Obj(pub Vec<(String, Js)>);

An object: fields in insertion order. Setting an existing field keeps its position, as in JavaScript.

Tuple Fields

0: Vec<(String, Js)>

Implementations

impl Obj

pub fn new() -> Obj

pub fn set(&mut self, key: &str, value: impl Into<Js>) -> &mut Obj

Appends or replaces key (keeping its position when it exists).

pub fn with(self, key: &str, value: impl Into<Js>) -> Obj

Builder form of Obj::set.

pub fn with_opt<T: Into<Js>>(self, key: &str, value: Option<T>) -> Obj

Sets key only when value is Some.

pub fn get(&self, key: &str) -> Option<&Js>

pub fn get_mut(&mut self, key: &str) -> Option<&mut Js>

pub fn remove(&mut self, key: &str) -> Option<Js>

pub fn num(&self, key: &str) -> f64

pub fn str(&self, key: &str) -> Option<&str>

pub fn bool(&self, key: &str) -> bool
