Struct Object 

pub struct Object { /* private fields */ }

A builder for one JSON object.

It writes the opening brace when the first field arrives, so an object that has no field is {} and not a broken one.

Implementations

impl Object

pub fn new(capacity: usize) -> Object

A new object, with room for fields of them.

pub fn field<F>(&mut self, name: &str, value: F) -> &mut Object

where F: FnOnce(&mut String),

Write the name of a field and its value, which the caller writes.

The value is written by the closure into the same buffer, so a field that is an array or another object nests without a value tree in between.

pub fn text(&mut self, name: &str, value: &str) -> &mut Object

Write a field whose value is a text.

pub fn number(&mut self, name: &str, value: i64) -> &mut Object

Write a field whose value is a whole number.

pub fn boolean(&mut self, name: &str, value: bool) -> &mut Object

Write a field whose value is a truth value.

pub fn nothing(&mut self, name: &str) -> &mut Object

Write a field whose value is null.

pub fn optional_number(&mut self, name: &str, value: Option<i64>) -> &mut Object

Write a field whose value is a whole number, or null when it is not there.

pub fn texts(&mut self, name: &str, values: &[String]) -> &mut Object

Write a field whose value is an array of texts.

pub fn finish(self) -> String

The object, as JSON.
