Struct Write 

pub struct Write<V, P = BTreeSet<WriteId>> {
    pub id: WriteId,
    pub timestamp: Timestamp,
    pub had_read: P,
    pub changes: BTreeMap<RowId, Change<V>>,
}

A decoded write’s merge inputs, independent of its storage encoding.

Fields

id: WriteId

Device and original write number.

timestamp: Timestamp

Unique total-order timestamp (§7.2).

had_read: P

The writes in the author’s read_through prefix and its own earlier writes (§7.1). Consuming a write does not imply retaining its row changes. The sequence resolves this relation from the prefix and own predecessors.

changes: BTreeMap<RowId, Change<V>>

At most one change for each table, key and audience.

Implementations

impl<V, P: WritePast> Write<V, P>

pub fn validate_metadata<O: WriteOracle>( &self, oracle: &O, ) -> Result<(), O::Error>

Check the write’s identity and causal timestamp against the applied set. This also validates writes with no row changes available to the receiver.

Trait Implementations

impl<V: Clone, P: Clone> Clone for Write<V, P>

fn clone(&self) -> Write<V, P>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<V: Debug, P: Debug> Debug for Write<V, P>

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

Formats the value using the given formatter.

impl<V: PartialEq, P: PartialEq> PartialEq for Write<V, P>

fn eq(&self, other: &Write<V, P>) -> 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.
