Struct Item

pub struct Item<'hir> {
    pub ident: Ident,
    pub owner_id: OwnerId,
    pub kind: ItemKind<'hir>,
    pub span: Span,
    pub vis_span: Span,
}

An item

The name might be a dummy name in case of anonymous items

For more details, see the rust lang reference. Note that the reference does not document nightly-only features. There may be also slight differences in the names and representation of AST nodes between the compiler and the reference.

Fields

ident: Ident

owner_id: OwnerId

kind: ItemKind<'hir>

span: Span

vis_span: Span

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.
