Trait rustc_ap_rustc_serialize::Decodable

pub trait Decodable<D: Decoder>: Sized {
    fn decode(d: &mut D) -> Result<Self, D::Error>;
}

Trait for types that can be deserialized

This can be implemented using the Decodable, TyDecodable and MetadataDecodable macros.

• Decodable should be used in crates that don’t depend on rustc_middle.
• MetadataDecodable is used in rustc_metadata for types that contain rustc_metadata::rmeta::Lazy.
• TyDecodable should be used for types that are only serialized in crate metadata or the incremental cache. This is most types in rustc_middle.
