Struct UpdatedAtStamper 

pub struct UpdatedAtStamper { /* private fields */ }

The database-owned _updated_at stamping capability over its shared Hlc.

The database creates it only while executing a host write. Pull advances the same Arc<Hlc>, so every later SqlContext::stamp observes that advance and cannot sort behind a pulled row.

It exposes only UpdatedAtStamper::stamp — never seed/advance_past/ high_water. Those drive the clock and are coven’s alone; the host write path is a pure consumer of stamps and must not poke clock state.

Implementations

impl UpdatedAtStamper

pub fn new(hlc: Arc<Hlc>) -> Self

pub fn stamp(&self) -> String

Mint the next _updated_at register value for a synced-row write. The returned string is an opaque HLC stamp; the host binds it into the write and must not parse or compare it as a wall-clock time.

Trait Implementations

impl Clone for UpdatedAtStamper

fn clone(&self) -> UpdatedAtStamper

Returns a duplicate of the value.

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

Performs copy-assignment from source.
