Implementations
sourceimpl SourceDesc
impl SourceDesc
sourcepub fn yields_stable_input(&self) -> bool
pub fn yields_stable_input(&self) -> bool
Returns true
if this connection yields input data (including
timestamps) that is stable across restarts. This is important for
exactly-once Sinks that need to ensure that the same data is written,
even when failures/restarts happen.
sourcepub fn append_only(&self) -> bool
pub fn append_only(&self) -> bool
Returns true
if this connection yields data that is
append-only/monotonic. Append-monly means the source
never produces retractions.
pub fn name(&self) -> &'static str
pub fn requires_single_materialization(&self) -> bool
