Struct ExternFn

pub struct ExternFn {
    pub doc: Option<Doc>,
    pub directives: Directives,
    pub name: Ident,
    pub params: Vec<Param>,
    pub return_type: Option<TypeExpr>,
    pub span: Span,
}

Expand description

ADR-0085: a body-less fn declaration that appears inside a link_extern block.

Bodies are forbidden here (the symbol is resolved at link time, not emitted from this compilation unit). Directives like @link_name still attach per-declaration.

Fields§

§doc: Option<Doc>

ADR-0089: docstring attached to this declaration.

§directives: Directives

Directives attached to this declaration (e.g. @link_name(...)).

§name: Ident

Function name as it appears in Gruel source.

§params: Vec<Param>

Parameters; comptime params are rejected by sema.

§return_type: Option<TypeExpr>

Return type (None means implicit unit ()).

§span: Span

Span covering the whole fn …; declaration.
