Enum OptRecordDiff 

pub enum OptRecordDiff<R>
where
    R: Node,
{
    Clear,
    Update(<R as Node>::Diff),
}

Represent a delta between two optional records X and Y.

Variants

Clear

To obtain Y from X, clear the optional record (if any)

Update(<R as Node>::Diff)

To obtain Y from X, apply the given diff on the record contained in X.

If X does not contain a record, the record diff represents the delta between the default value R and the value contained in Y.

Trait Implementations

impl<R> Clone for OptRecordDiff<R>

where R: Clone + Node, <R as Node>::Diff: Clone,

fn clone(&self) -> OptRecordDiff<R>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<R> Debug for OptRecordDiff<R>

where R: Debug + Node, <R as Node>::Diff: Debug,

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

Formats the value using the given formatter.

impl<'de, R> Deserialize<'de> for OptRecordDiff<R>

where R: Node, <R as Node>::Diff: Deserialize<'de>,

fn deserialize<__D>( __deserializer: __D, ) -> Result<OptRecordDiff<R>, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<R> Hash for OptRecordDiff<R>

where R: Hash + Node, <R as Node>::Diff: Hash,

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<R> PartialEq for OptRecordDiff<R>

where R: PartialEq + Node, <R as Node>::Diff: PartialEq,

fn eq(&self, other: &OptRecordDiff<R>) -> bool

Tests for self and other values to be equal, and is used by ==.

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

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

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<R> Eq for OptRecordDiff<R>

where R: Eq + Node, <R as Node>::Diff: Eq,

impl<R> StructuralPartialEq for OptRecordDiff<R>

where R: Node,
