Struct ExprTuple

#[non_exhaustive]
pub struct ExprTuple {
    pub attributes: Vec<Attribute>,
    pub items: Parenthesized<Expr, Comma>,
}

An expression to construct a literal tuple.

• (<expr>,*).

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>

Attributes associated with tuple.

items: Parenthesized<Expr, Comma>

Items in the tuple.

Implementations

impl ExprTuple

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

Parse #ident and attach the given meta

Trait Implementations

impl Debug for ExprTuple

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

Formats the value using the given formatter.

impl OptionSpanned for ExprTuple

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

Get the optional span of the type.

impl Parse for ExprTuple

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

Parse the current item from the parser.

impl PartialEq for ExprTuple

fn eq(&self, other: &ExprTuple) -> 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 ExprTuple

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for ExprTuple

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

Turn the current item into tokens.

impl TryClone for ExprTuple

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 ExprTuple
