Struct mz_persist_client::internal::trace::MergeState
source · struct MergeState<T> {
batches: ArrayVec<SpineBatch<T>, BATCHES_PER_LEVEL>,
merge: Option<IdFuelingMerge<T>>,
}
Expand description
Describes the state of a layer.
A layer can be empty, contain a single batch, or contain a pair of batches that are in the process of merging into a batch for the next layer.
Fields§
§batches: ArrayVec<SpineBatch<T>, BATCHES_PER_LEVEL>
§merge: Option<IdFuelingMerge<T>>
Implementations§
source§impl<T: Timestamp + Lattice> MergeState<T>
impl<T: Timestamp + Lattice> MergeState<T>
sourcefn id(&self) -> Option<SpineId>
fn id(&self) -> Option<SpineId>
An id that covers all the batches in the given merge state, assuming there are any.
sourcefn single(batch: SpineBatch<T>) -> Self
fn single(batch: SpineBatch<T>) -> Self
A new single-batch merge state.
sourcefn push_batch(&mut self, batch: SpineBatch<T>)
fn push_batch(&mut self, batch: SpineBatch<T>)
Push a new batch at this level, checking invariants.
sourcefn is_full(&self) -> bool
fn is_full(&self) -> bool
True if this merge cannot hold any more batches. (i.e. for a binary merge tree, true if this layer holds two batches.)
sourcefn complete(&mut self, log: &mut SpineLog<'_, T>) -> Option<SpineBatch<T>>
fn complete(&mut self, log: &mut SpineLog<'_, T>) -> Option<SpineBatch<T>>
Immediately complete any merge.
The result is either a batch, if there is a non-trivial batch to return
or None
if there is no meaningful batch to return.
There is the additional option of input batches.
sourcefn is_complete(&self) -> bool
fn is_complete(&self) -> bool
True iff the layer is a complete merge, ready for extraction.
