Trait Implementations

impl AstLike for AttrItem

const SUPPORTS_CUSTOM_INNER_ATTRS: bool

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

fn attrs(&self) -> &[Attribute]

fn visit_attrs(&mut self, _f: impl FnOnce(&mut Vec<Attribute>))

fn tokens_mut(&mut self) -> Option<&mut Option<LazyTokenStream>>

impl Clone for AttrItem

fn clone(&self) -> AttrItem

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AttrItem

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
