Struct syntax::ast::Item

pub struct Item {
    pub ident: Ident,
    pub attrs: Vec<Attribute>,
    pub id: NodeId,
    pub node: ItemKind,
    pub vis: Visibility,
    pub span: Span,
    pub tokens: Option<TokenStream>,
}

An item.

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

Fields

ident: Ident

attrs: Vec<Attribute>

id: NodeId

node: ItemKind

vis: Visibility

span: Span

tokens: Option<TokenStream>

Original tokens this item was parsed from. This isn't necessarily available for all items, although over time more and more items should have this be Some. Right now this is primarily used for procedural macros, notably custom attributes.

Note that the tokens here do not include the outer attributes, but will include inner attributes.

Methods

impl Item

pub fn span_with_attributes(&self) -> Span

Return the span that encompasses the attributes.
