Item(P<Item>)

An item definition.

Trait Implementations

impl Clone for StmtKind

fn clone(&self) -> StmtKind

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StmtKind

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

Formats the value using the given formatter.

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

fn decode(__decoder: &mut __D) -> Self

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

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

impl HasAttrs for StmtKind

const SUPPORTS_CUSTOM_INNER_ATTRS: bool = true

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 AttrVec))

impl HasTokens for StmtKind

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

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

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.
