Struct rustc_serialize::json::Encoder

pub struct Encoder<'a> {
    // some fields omitted
}

A structure for implementing serialization to JSON.

Methods

impl<'a> Encoder<'a>

fn new_pretty(writer: &'a mut Write) -> Encoder<'a>

Creates a new encoder whose output will be written in human-readable JSON to the specified writer

fn new(writer: &'a mut Write) -> Encoder<'a>

Creates a new encoder whose output will be written in compact JSON to the specified writer

fn set_indent(&mut self, new_indent: u32) -> Result<(), ()>

Set the number of spaces to indent for each level. This is safe to set during encoding.
