The CRUD operation type

Variants

Create(EventContent<'a, T>)

Implementations

impl<'a, T> Event<'a, T>

where T: Clone + PartialEq,

pub fn create(data: Cow<'a, T>) -> Self

Constructs a new create event

pub fn update(data: Cow<'a, T>) -> Self

Constructs a new update event

pub fn delete(data: Cow<'a, T>) -> Self

Constructs a new delete event

pub fn get_time(&self) -> &Timestamp

Borrow the date of the event

pub fn take(self) -> Cow<'a, T>

Consumes the event, returning the contained data

Trait Implementations

impl<'a, T> Clone for Event<'a, T>

where T: Clone + PartialEq + Clone,

fn clone(&self) -> Event<'a, T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a, T> Debug for Event<'a, T>

where T: Clone + PartialEq + Debug,

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

Formats the value using the given formatter.

impl<'a, T> Deref for Event<'a, T>

where T: Clone + PartialEq,

type Target = T

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de, 'a, T> Deserialize<'de> for Event<'a, T>

where T: Clone + PartialEq + Deserialize<'de>,

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<'a, T> PartialEq for Event<'a, T>

where T: Clone + PartialEq + PartialEq,

fn eq(&self, other: &Event<'a, T>) -> 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.

impl<'a, T> PartialOrd for Event<'a, T>

where T: Clone + PartialEq,

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl<'a, T> Serialize for Event<'a, T>

where T: Clone + PartialEq + Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl<'a, T> StructuralPartialEq for Event<'a, T>

where T: Clone + PartialEq,
