    AtLeast(u32),
    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.
