Struct mergable::Counter

pub struct Counter<V, Seq> { /* private fields */ }

A counter.

Implementations

impl<V, SF: SequenceFactory> Counter<V, Sequence<SF>>

pub fn new(ctx: &mut Context<SF>, value: V) -> Selfwhere V: Clone,

pub fn add(&mut self, ctx: &mut Context<SF>, value: V)where V: for<'a> AddAssign<&'a V> + AddAssign<V>,

Set this session’s value

This will overwrite any existing values.

pub fn total(&self) -> &V

Trait Implementations

impl<V: Clone, Seq: Clone> Clone for Counter<V, Seq>

fn clone(&self) -> Counter<V, Seq>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<V: Debug, Seq: Debug> Debug for Counter<V, Seq>

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

Formats the value using the given formatter.

impl<V: Default, SF: SequenceFactory> Default for Counter<V, Sequence<SF>>

fn default() -> Self

Returns the “default value” for a type.

impl<V: Clone + for<'a> AddAssign<&'a V> + for<'a> SubAssign<&'a V>, SF: SequenceFactory> Mergable for Counter<V, Sequence<SF>>

type Diff = CounterDiff<V, Sequence<SF>>

type Seq = Sequence<SF>

fn diff(&self, that: &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.

fn merge(&mut self, other: Self)

impl<V: PartialEq, Seq> PartialEq<Counter<V, Seq>> for Counter<V, 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.
