Struct rustc_builtin_macros::deriving::generic::Substructure

pub struct Substructure<'a> {
    pub type_ident: Ident,
    pub nonselflike_args: &'a [P<Expr>],
    pub fields: &'a SubstructureFields<'a>,
}

All the data about the data structure/method being derived upon.

Fields

type_ident: Ident

ident of self

nonselflike_args: &'a [P<Expr>]

Verbatim access to any non-selflike arguments, i.e. arguments that don’t have type &Self.

fields: &'a SubstructureFields<'a>

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
