Struct chronofold::Session

pub struct Session<'a, A: Author, T> { /* fields omitted */ }

An editing session tied to one author.

Session provides a lot of functions you might know from Vec or VecDeque. Under the hood, Session will append changes to the chronofolds log.

Note that Session has a mutable (exclusive) borrow of a chronofold. So Rust's ownership rules enforce that there is always just one Session per chronofold.

Implementations

impl<'a, A: Author, T: Debug> Session<'a, A, T>

pub fn new(author: A, chronofold: &'a mut Chronofold<A, T>) -> Self

Creates an editing session for a single author.

pub fn clear(&mut self)

Clears the chronofold, removing all elements.

pub fn push_back(&mut self, value: T) -> LogIndex

Appends an element to the back of the chronofold and returns the new element's log index.

pub fn push_front(&mut self, value: T) -> LogIndex

Prepends an element to the chronofold and returns the new element's log index.

pub fn insert_after(&mut self, index: Option<LogIndex>, value: T) -> LogIndex

Inserts an element after the element with log index index and returns the new element's log index.

If index == None, the element will be inserted at the beginning.

pub fn remove(&mut self, index: LogIndex)

Removes the element with log index index from the chronofold.

Note that this just marks the element as deleted, not actually modify the log apart from appending a Change::Delete.

pub fn extend<I: IntoIterator<Item = T>>(&mut self, iter: I) -> Option<LogIndex>

Extends the chronofold with the contents of iter, returns the log index of the last inserted element, if any.

pub fn splice<R, I>(&mut self, range: R, replace_with: I) -> Option<LogIndex> where
    I: IntoIterator<Item = T>,
    R: RangeBounds<LogIndex>, 

Replaces the specified range in the chronofold with the given replace_with iterator and returns the log index of the last inserted element, if any.

impl<'a, A: Author, T: Clone> Session<'a, A, T>

pub fn iter_ops(&'a self) -> impl Iterator<Item = Op<A, T>> + 'a

Returns an iterator over ops in log order, that where created in this session.
