Implementations

impl RangeExpr

pub fn is_constant(&self) -> bool

pub fn to_slice_range(&self) -> Range

Converts this range expression to a Range type, assuming it is constant. Panics if the range is not constant.

pub fn ty(&self) -> Option<Type>

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 Display for RangeExpr

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

Formats the value using the given formatter.

impl From<Range<usize>> for RangeExpr

fn from(range: Range) -> Self

Converts to this type from the input type.

impl Hash for RangeExpr

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for RangeExpr

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

fn span(&self) -> SourceSpan

impl TryFrom<&RangeExpr> for Range

type Error = InvalidExprError

The type returned in the event of a conversion error.

fn try_from(expr: &RangeExpr) -> Result<Self, InvalidExprError>

Performs the conversion.
