Struct iodyn::raz::Raz

pub struct Raz<E: Debug + Clone + Eq + Hash + 'static, M: RazMeta<E> + 'static> { /* fields omitted */ }

Random access zipper

A cursor into a sequence

Methods

impl<E: Debug + Clone + Eq + Hash + 'static, M: RazMeta<E>> Raz<E, M>

fn new() -> Raz<E, M>

Create a new RAZ, for an empty sequence

fn unfocus(self) -> RazTree<E, M>

unfocus the RazTree before refocusing on a new location in the sequence.

fn push_left(&mut self, elm: E) -> usize

add an element to the left of the cursor

returns number of non-archived elements

fn push_right(&mut self, elm: E) -> usize

add an element to the right of the cursor

returns number of non-archived elements

fn peek_left(&self) -> Option<E>

peek at the element to the left of the cursor

fn peek_right(&self) -> Option<E>

peek at the element to the left of the cursor

fn archive_left(&mut self, level: u32, name: Option<Name>)

mark the data at the left to be part of a subsequence

fn archive_right(&mut self, level: u32, name: Option<Name>)

mark the data at the right to be part of a subsequence

fn pop_left(&mut self) -> Option<E>

remove and return an element to the left of the cursor

if an archive point is to the left of the cursor, it will be removed

fn pop_right(&mut self) -> Option<E>

remove and return an element to the right of the cursor

if an archive point is to the right of the cursor, it will be removed
