Enum Json 

pub enum Json {
    Null,
    Bool(bool),
    Int(i64),
    Num(String),
    Str(String),
    Arr(Vec<Json>),
    Obj(Vec<(String, Json)>),
}

Small JSON value (for the manifest).

Variants

Null

null.

Bool(bool)

Boolean.

Int(i64)

Integer.

Num(String)

An already formatted number (Python round result).

Str(String)

String.

Arr(Vec<Json>)

Array.

Obj(Vec<(String, Json)>)

Object (key order preserved).

Implementations

impl Json

pub fn obj(items: Vec<(&str, Json)>) -> Json

Object from a (key, value) list.

pub fn f(x: f64, digits: i32) -> Json

Number rounded to digits decimal places.

pub fn of(x: Option<f64>, digits: i32) -> Json

Number or null.

pub fn ints(v: &[usize]) -> Json

Integer array.

pub fn dump(&self) -> String

Shape of json.dump(..., indent=1, ensure_ascii=False).

pub fn py_repr(&self) -> String

Shape of Python dict/list repr (for summary output).

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

Look up an object’s key.

pub fn as_f64(&self) -> Option<f64>

f64 if a number (integer or float).

pub fn parse(text: &str) -> Result<Json, String>

Read JSON text (standard syntax; numbers keep their original text in Json::Num, or Json::Int if integer-shaped).

Trait Implementations

impl Clone for Json

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Json

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
