Struct IndexExpr 

pub struct IndexExpr {
    pub base: Box<Expr>,
    pub index: Box<Expr>,
    pub span: Span,
}

An array index expression (e.g., arr[0]).

Fields

base: Box<Expr>

The array being indexed

index: Box<Expr>

The index expression. May be Expr::Range(_) for slice subscripts (ADR-0064); sema enforces that range subscripts appear only as the place under & / &mut.

span: Span

Trait Implementations

impl Clone for IndexExpr

fn clone(&self) -> IndexExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IndexExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IndexExpr

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for IndexExpr

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

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 IndexExpr

impl StructuralPartialEq for IndexExpr
