Struct ExprAssign

#[non_exhaustive]
pub struct ExprAssign {
    pub attributes: Vec<Attribute>,
    pub lhs: Box<Expr>,
    pub eq: Eq,
    pub rhs: Box<Expr>,
}

An assign expression.

• a = b.

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 the assign expression.

lhs: Box<Expr>

The expression being assigned to.

eq: Eq

The equals sign =.

rhs: Box<Expr>

The value.

Trait Implementations

impl Debug for ExprAssign

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

Formats the value using the given formatter.

impl OptionSpanned for ExprAssign

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

Get the optional span of the type.

impl Parse for ExprAssign

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

Parse the current item from the parser.

impl PartialEq for ExprAssign

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

fn span(&self) -> Span

Get the span of the type.

impl ToTokens for ExprAssign

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

Turn the current item into tokens.

impl TryClone for ExprAssign

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 ExprAssign

impl StructuralPartialEq for ExprAssign
