Module rustc_builtin_macros::deriving
source · Expand description
The compiler code necessary to implement the #[derive]
extensions.
Modules
- The compiler code necessary for
#[derive(RustcDecodable)]
. See encodable.rs for more. - The compiler code necessary to implement the
#[derive(RustcEncodable)]
(andRustcDecodable
, indecodable.rs
) extension. The idea here is that type-defining items may be tagged with#[derive(RustcEncodable, RustcDecodable)]
. - Some code that abstracts away much of the boilerplate of writing
derive
instances for traits. Among other things it manages getting access to the fields of the 4 different sorts of structs and enum variants, as well as creating the method and impl ast instances.
Macros

Structs
Functions
- Constructs an expression that calls an intrinsic
- Constructs an expression that calls the

intrinsic.
