Enum differential_dataflow::capture::Message

pub enum Message<D, T, R> {
    Updates(Vec<(D, T, R)>),
    Progress(Progress<T>),
}

A message in the CDC V2 protocol.

Variants

Updates(Vec<(D, T, R)>)

A batch of updates that are certain to occur.

Each triple is an irrevocable statement about a change that occurs. Each statement contains a datum, a time, and a difference, and asserts that the multiplicity of the datum changes at the time by the difference.

Progress(Progress<T>)

An irrevocable statement about the number of updates within a time interval.

Trait Implementations

impl<D, T, R> Abomonation for Message<D, T, R>

where Vec<(D, T, R)>: Abomonation, D: Abomonation, T: Abomonation, R: Abomonation, Progress<T>: Abomonation,

unsafe fn entomb<W: Write>(&self, _write: &mut W) -> Result<()>

Write any additional information about &self beyond its binary representation.

Reports the number of further bytes required to entomb self.

unsafe fn exhume<'a, 'b>( &'a mut self, bytes: &'b mut [u8] ) -> Option<&'b mut [u8]>

Recover any information for &mut self not evident from its binary representation.

impl<D: Clone, T: Clone, R: Clone> Clone for Message<D, T, R>

fn clone(&self) -> Message<D, T, R>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<D: Debug, T: Debug, R: Debug> Debug for Message<D, T, R>

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

Formats the value using the given formatter.

impl<'de, D, T, R> Deserialize<'de> for Message<D, T, R>

where D: Deserialize<'de>, T: Deserialize<'de>, R: Deserialize<'de>,

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl<D: Ord, T: Ord, R: Ord> Ord for Message<D, T, R>

fn cmp(&self, other: &Message<D, T, R>) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl<D: PartialEq, T: PartialEq, R: PartialEq> PartialEq for Message<D, T, R>

fn eq(&self, other: &Message<D, T, R>) -> 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<D: PartialOrd, T: PartialOrd, R: PartialOrd> PartialOrd for Message<D, T, R>

fn partial_cmp(&self, other: &Message<D, T, R>) -> Option<Ordering>

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl<D, T, R> Serialize for Message<D, T, R>

where D: Serialize, T: Serialize, R: Serialize,

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
