Implementations

impl AttrItem

pub fn span(&self) -> Span

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

pub fn meta_kind(&self) -> Option<MetaItemKind>

Trait Implementations

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) -> Self

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

fn encode(&self, __encoder: &mut __E)

impl HasAttrs for AttrItem

const SUPPORTS_CUSTOM_INNER_ATTRS: bool = false

This is true if this HasAttrs 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>))

impl HasSpan for AttrItem

fn span(&self) -> Span

impl HasTokens for AttrItem

fn tokens(&self) -> Option<&LazyTokenStream>

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

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.
