Expand description

An item definition.

Fields

attrs: Vec<Attribute>id: NodeIdspan: Spanvis: Visibilityident: Ident

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

kind: Ktokens: Option<LazyTokenStream>

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.

Implementations

Return the span that encompasses the attributes.

Trait Implementations

This is true if this AstLike might support ‘custom’ (proc-macro) inner attributes. Attributes like #![cfg] and #![cfg_attr] are not considered ‘custom’ attributes Read more

Layout

Note: Unable to compute type layout, possibly due to this type having generic parameters. Layout can only be computed for concrete, fully-instantiated types.
