Struct ExprLoop

#[non_exhaustive]
pub struct ExprLoop {
    pub attributes: Vec<Attribute>,
    pub label: Option<(Label, Colon)>,
    pub loop_token: Loop,
    pub body: Box<Block>,
}

A loop expression.

• loop { ... }.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

attributes: Vec<Attribute>

The attributes for the loop

label: Option<(Label, Colon)>

A label followed by a colon.

loop_token: Loop

The loop keyword.

body: Box<Block>

The body of the loop.

Implementations

impl ExprLoop

pub fn parse_with_meta( parser: &mut Parser<'_>, attributes: Vec<Attribute>, label: Option<(Label, Colon)>, ) -> Result<Self, Error>

Parse #ident and attach the given meta

Trait Implementations

impl Debug for ExprLoop

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

Formats the value using the given formatter.

impl OptionSpanned for ExprLoop

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

Get the optional span of the type.

impl Parse for ExprLoop

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

Parse the current item from the parser.

impl PartialEq for ExprLoop

fn eq(&self, other: &ExprLoop) -> 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 Spanned for ExprLoop

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for ExprLoop

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

Turn the current item into tokens.

impl TryClone for ExprLoop

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 ExprLoop

impl StructuralPartialEq for ExprLoop
