Struct cfg::sequence::Sequence

pub struct Sequence<H> {
    pub lhs: Symbol,
    pub rhs: Symbol,
    pub start: u32,
    pub end: Option<u32>,
    pub separator: Separator,
    pub history: H,
}

Sequence rule representation.

Fields

lhs: Symbol

The rule's left-hand side.

rhs: Symbol

The rule's right-hand side.

start: u32

The minimum number of repetitions.

end: Option<u32>

Either the inclusive maximum number of repetitions, or None if the number of repetitions is unlimited.

separator: Separator

The way elements are separated in a sequence, or Null.

history: H

The history carried with the sequence rule.

Methods

impl<H> Sequence<H>

pub fn inclusive(self, start: u32, end: Option<u32>) -> Self

Assigns the inclusive range of the number of repetitions.

pub fn separator(self, sep: Separator) -> Self

Assigns the separator symbol and mode of separation.

Trait Implementations

impl<H: Clone> Clone for Sequence<H>

fn clone(&self) -> Sequence<H>
