DeriveDecl

gruel_parser::ast

Struct DeriveDecl

pub struct DeriveDecl {
    pub doc: Option<Doc>,
    pub name: Ident,
    pub methods: Vec<Method>,
    pub span: Span,
}

Expand description

A derive declaration (ADR-0058).

Holds a list of method declarations whose body refers to the host type as Self. Methods are spliced into a host type’s method list when a @derive(Name) directive on a struct or enum names this derive.

derive Drop {
    fn __drop(self) {
        comptime_unroll for f in @type_info(Self).fields {
            drop(@field(self, f.name));
        }
    }
}

Fields§

§doc: Option<Doc>

ADR-0089: docstring attached to this derive.

§name: Ident

Derive name (e.g., Drop)

§methods: Vec<Method>

Method declarations inside the derive body

§span: Span

Span covering the entire derive item
