Struct RangeExpr 

pub struct RangeExpr {
    pub lo: Option<Box<Expr>>,
    pub hi: Option<Box<Expr>>,
    pub span: Span,
}

A range expression used as a slice subscript (ADR-0064).

Ranges are recognized only inside [ … ]. lo and hi are optional (defaulting to 0 and arr.len() respectively).

Fields

lo: Option<Box<Expr>>

hi: Option<Box<Expr>>

span: Span

Trait Implementations

impl Clone for RangeExpr

fn clone(&self) -> RangeExpr

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RangeExpr

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for RangeExpr

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for RangeExpr

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

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 RangeExpr
