Struct TupleIndexExpr 

pub struct TupleIndexExpr {
    pub base: Box<Expr>,
    pub index: u32,
    pub span: Span,
    pub index_span: Span,
}

A tuple index expression (e.g., t.0, t.1).

Fields

base: Box<Expr>

Base expression (the tuple value)

index: u32

Numeric index (0-based)

span: Span

Span of the whole expression (base through the index token)

index_span: Span

Span of just the index token (for diagnostics)

Trait Implementations

impl Clone for TupleIndexExpr

fn clone(&self) -> TupleIndexExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TupleIndexExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TupleIndexExpr

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for TupleIndexExpr

fn eq(&self, other: &TupleIndexExpr) -> 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 Serialize for TupleIndexExpr

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for TupleIndexExpr

impl StructuralPartialEq for TupleIndexExpr
