Struct WriteHeader 

pub struct WriteHeader {
    pub position: WriteId,
    pub timestamp: Timestamp,
    pub read_through: u64,
    pub schema_version: u32,
    pub disposition: WriteDisposition,
}

Identity, timestamp, read-through slot and schema of a transaction.

Fields

position: WriteId

Which device wrote it and its original local write number.

timestamp: Timestamp

The author’s timestamp, whose device matches the write identity.

read_through: u64

Last applied slot when authored; own earlier writes are implicit reads.

schema_version: u32

The app schema version (§18).

disposition: WriteDisposition

An ordinary write or a breaking migration marker; exclusion is decided on receipt.

Trait Implementations

impl Clone for WriteHeader

fn clone(&self) -> WriteHeader

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for WriteHeader

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

Formats the value using the given formatter.

impl PartialEq for WriteHeader

fn eq(&self, other: &WriteHeader) -> 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.
