Trait rustc_serialize::Encodable[][src]

pub trait Encodable {
    fn encode<S: Encoder>(&self, s: &mut S) -> Result<(), S::Error>;
}

Trait for serializing a type.

This can be implemented for custom data types to allow them to be encoded with Encoder implementations. Most of Rust's built-in or standard data types (like i32 and Vec<T>) have Encodable implementations provided by this module.

Note that, in general, you should let the compiler implement this for you by using the derive(RustcEncodable) attribute.

Examples

extern crate rustc_serialize;

#[derive(RustcEncodable)]
struct Point {
    x: i32,
    y: i32,
}

This generates code equivalent to:

extern crate rustc_serialize;
use rustc_serialize::Encodable;
use rustc_serialize::Encoder;

struct Point {
    x: i32,
    y: i32,
}

impl Encodable for Point {
    fn encode<S: Encoder>(&self, s: &mut S) -> Result<(), S::Error> {
        s.emit_struct("Point", 2, |s| {
            try!(s.emit_struct_field("x", 0, |s| {
                s.emit_i32(self.x)
            }));
            try!(s.emit_struct_field("y", 1, |s| {
                s.emit_i32(self.y)
            }));
            Ok(())
        })
    }
}
