Enum Stmt

#[non_exhaustive]
pub enum Stmt {
    Local(Box<Local>),
    Item(Item, Option<SemiColon>),
    Expr(Expr),
    Semi(StmtSemi),
}

A statement within a block.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Local(Box<Local>)

A local declaration.

Item(Item, Option<SemiColon>)

A declaration.

Expr(Expr)

An expression.

Semi(StmtSemi)

An with a trailing semi-colon.

And absent semicolon indicates that it is synthetic.

Trait Implementations

impl Debug for Stmt

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

Formats the value using the given formatter.

impl OptionSpanned for Stmt

fn option_span(&self) -> Option<Span>

Get the optional span of the type.

impl Parse for Stmt

fn parse(p: &mut Parser<'_>) -> Result<Self, Error>

Parse the current item from the parser.

impl PartialEq for Stmt

fn eq(&self, other: &Stmt) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Peek for Stmt

fn peek(p: &mut Peeker<'_>) -> bool

Peek the parser for the given token.

impl Spanned for Stmt

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for Stmt

fn to_tokens( &self, context: &mut MacroContext<'_, '_, '_>, stream: &mut TokenStream, ) -> Result<()>

Turn the current item into tokens.

impl TryClone for Stmt

fn try_clone(&self) -> Result<Self>

Try to clone the current value, raising an allocation error if it’s unsuccessful.

fn try_clone_from(&mut self, source: &Self) -> Result<(), Error>

Performs copy-assignment from source.

impl Eq for Stmt
