Trait rustc_serialize::Decodable [−][src]
Trait for deserializing a type.
This can be implemented for custom data types to allow them to be decoded
with Decoder
implementations. Most of Rust's built-in or standard data
types (like i32
and Vec<T>
) have Decodable
implementations provided by
this module.
Note that, in general, you should let the compiler implement this for you by
using the derive(RustcDecodable)
attribute.
Examples
extern crate rustc_serialize; #[derive(RustcDecodable)] struct Point { x: i32, y: i32, }
This generates code equivalent to:
extern crate rustc_serialize; use rustc_serialize::Decodable; use rustc_serialize::Decoder; struct Point { x: i32, y: i32, } impl Decodable for Point { fn decode<D: Decoder>(d: &mut D) -> Result<Point, D::Error> { d.read_struct("Point", 2, |d| { let x = try!(d.read_struct_field("x", 0, |d| { d.read_i32() })); let y = try!(d.read_struct_field("y", 1, |d| { d.read_i32() })); Ok(Point{ x: x, y: y }) }) } }
