Struct RepetitionKind

pub struct RepetitionKind {
    pub lower_bound: u32,
    pub upper_bound: Option<u32>,
}

A repetition in its most canonical form, {x,y}.

For example:

• 'x'? is equivalent to 'x'{0,1}
• 'x'+ is equivalent to 'x'{1,}
• 'x'* is equivalent to 'x'{0,}

Fields

lower_bound: u32

The lower bound, e.g. {4,}

upper_bound: Option<u32>

The upper bound, e.g. {0,7}. None means infinity.

Trait Implementations

impl Clone for RepetitionKind

fn clone(&self) -> RepetitionKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for RepetitionKind

fn default() -> RepetitionKind

Returns the “default value” for a type.

impl PartialEq for RepetitionKind

fn eq(&self, other: &RepetitionKind) -> 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 TryFrom<(u32, Option<u32>)> for RepetitionKind

type Error = RepetitionError

The type returned in the event of a conversion error.

fn try_from( (lower_bound, upper_bound): (u32, Option<u32>), ) -> Result<Self, Self::Error>

Performs the conversion.
