Enum RepetitionRange

pub enum RepetitionRange {
    Exactly(u32),
    AtLeast(u32),
    Bounded(u32, u32),
}

A range repetition operator.

Variants

Exactly(u32)

{m}

AtLeast(u32)

{m,}

Bounded(u32, u32)

{m,n}

Implementations

impl RepetitionRange

pub fn is_valid(&self) -> bool

Returns true if and only if this repetition range is valid.

The only case where a repetition range is invalid is if it is bounded and its start is greater than its end.

Trait Implementations

impl Clone for RepetitionRange

fn clone(&self) -> RepetitionRange

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RepetitionRange

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

Formats the value using the given formatter.

impl PartialEq for RepetitionRange

fn eq(&self, other: &RepetitionRange) -> 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 Eq for RepetitionRange

impl StructuralPartialEq for RepetitionRange

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
