Struct rustc_serialize::json::Encoder

pub struct Encoder<'a> {
    writer: &'a mut (dyn Write + 'a),
    is_emitting_map_key: bool,
}

A structure for implementing serialization to JSON.

Fields

writer: &'a mut (dyn Write + 'a)

is_emitting_map_key: bool

Implementations

impl<'a> Encoder<'a>

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

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

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference’s “Type Layout” chapter for details on type layout guarantees.
