Module syntax_ext::deriving[−][src]

🔬 This is a nightly-only experimental API. (rustc_private)

this crate is being loaded from the sysroot, an unstable location; did you mean to load this crate from crates.io via Cargo.toml instead?

The compiler code necessary to implement the #[derive] extensions.

bounds	[ Experimental ]
clone	[ Experimental ]
custom	[ Experimental ]
debug	[ Experimental ]
decodable	[ Experimental ] The compiler code necessary for `#[derive(Decodable)]`. See encodable.rs for more.
default	[ Experimental ]
encodable	[ Experimental ] The compiler code necessary to implement the `#[derive(Encodable)]` (and `Decodable`, in decodable.rs) extension. The idea here is that type-defining items may be tagged with `#[derive(Encodable, Decodable)]`.
eq	[ Experimental ]
generic	[ Experimental ] 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.
hash	[ Experimental ]
ord	[ Experimental ]
partial_eq	[ Experimental ]
partial_ord	[ Experimental ]

call_intrinsic	[ Experimental ] Constructs an expression that calls an intrinsic
hygienic_type_parameter	[ Experimental ] Construct a name for the inner type parameter that can't collide with any type parameters of the item. This is achieved by starting with a base and then concatenating the names of all other type parameters.
is_builtin_trait	[ Experimental ]
register_builtin_derives	[ Experimental ]
warn_if_deprecated	[ Experimental ]
