pub fn meta(&self, span: Span) -> Option<MetaItem>

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.

impl<__D: Decoder> Decodable<__D> for AttrItem

fn decode(__decoder: &mut __D) -> Result<Self, <__D as Decoder>::Error>

impl<__E: Encoder> Encodable<__E> for AttrItem

fn encode(&self, __encoder: &mut __E) -> Result<(), <__E as Encoder>::Error>

impl<__CTX> HashStable<__CTX> for AttrItem where
    __CTX: HashStableContext, 

fn hash_stable(&self, __hcx: &mut __CTX, __hasher: &mut StableHasher)

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.
