Trait Implementations

impl<T> Clone for Deletable<T>where T: Clone,

fn clone(&self) -> Deletable<T>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T> Crdt for Deletable<T>where T: Crdt,

fn merge(&mut self, other: &Deletable<T>)

Merge the two datastructures according to the CRDT rules. self is modified to contain the merged CRDT value. other is not modified.

impl<T> Debug for Deletable<T>where T: Debug,

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

Formats the value using the given formatter.

impl<'de, T> Deserialize<'de> for Deletable<T>where T: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D ) -> Result<Deletable<T>, <__D as Deserializer<'de>>::Error>where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<T> From<Option<T>> for Deletable<T>

fn from(v: Option<T>) -> Deletable<T>

Converts to this type from the input type.

impl<T> PartialEq<Deletable<T>> for Deletable<T>where T: PartialEq<T>,

fn eq(&self, other: &Deletable<T>) -> 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.

impl<T> Serialize for Deletable<T>where T: Serialize,

fn serialize<__S>( &self, __serializer: __S ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<T> Copy for Deletable<T>where T: Copy,

impl<T> Eq for Deletable<T>where T: Eq,

impl<T> StructuralEq for Deletable<T>

impl<T> StructuralPartialEq for Deletable<T>
