Struct mergable::Cell

pub struct Cell<T, Seq> { /* private fields */ }

Implementations

impl<T, SequenceFactory: SequenceFactory> Cell<T, Sequence<SequenceFactory>>

pub fn new(ctx: &mut Context<SequenceFactory>, value: T) -> Self

pub fn set(&mut self, ctx: &mut Context<SequenceFactory>, value: T)

pub fn last_modified(&self) -> &Sequence<SequenceFactory>

pub fn borrow_mut(&mut self, ctx: &mut Context<SequenceFactory>) -> &mut T

Mutably borrow the cell.

Note that the following lines are equivalent. The benefit of borrow_mut() is for values that are not (cheaply) clonable.

*cell.borrow_mut(&mut ctx) += 1;
cell.set(&mut ctx, *cell.clone() + 1);

pub fn into(self) -> T

Trait Implementations

impl<T: Clone, SF: Clone> Clone for Cell<T, SF>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T: Debug, Seq> Debug for Cell<T, Seq>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<T, SF> Deref for Cell<T, SF>

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &T

Dereferences the value.

impl<T: Clone, SequenceFactory: SequenceFactory> Mergable for Cell<T, Sequence<SequenceFactory>>

type Diff = CellDiff<T, Sequence<SequenceFactory>>

type Seq = Sequence<SequenceFactory>

fn merge(&mut self, other: Self)

fn diff(&self, other: &Self) -> Self::Diff

Produce a diff.

fn apply(&mut self, diff: Self::Diff) -> Result<(), ApplyError>

fn clean(&mut self, _cutoff: &Self::Seq)

Clean up history.

impl<T: PartialEq, Seq> PartialEq<Cell<T, Seq>> for Cell<T, Seq>

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
