Description
Incremental construction functionality for the general-purpose fence pointer index.
Synopsis
- data IndexOrdinaryAcc s = IndexOrdinaryAcc !(GrowingVector s SerialisedKey) !(Baler s)
- new :: Int -> Int -> ST s (IndexOrdinaryAcc s)
- newWithDefaults :: ST s (IndexOrdinaryAcc s)
- appendSingle :: (SerialisedKey, SerialisedKey) -> IndexOrdinaryAcc s -> ST s (Maybe Chunk)
- appendMulti :: (SerialisedKey, Word32) -> IndexOrdinaryAcc s -> ST s [Chunk]
- unsafeEnd :: IndexOrdinaryAcc s -> ST s (Maybe Chunk, IndexOrdinary)
Documentation
data IndexOrdinaryAcc s Source #
A general-purpose fence pointer index under incremental construction.
A value IndexOrdinaryAcc lastKeys baler denotes a partially constructed
index that assigns keys to pages according to lastKeys and uses baler
for incremental output of the serialised key list.
Constructors
| IndexOrdinaryAcc !(GrowingVector s SerialisedKey) !(Baler s) |
Arguments
| :: Int | Initial size of the key buffer |
| -> Int | Minimum chunk size in bytes |
| -> ST s (IndexOrdinaryAcc s) | Construction of the index |
Creates a new, initially empty, index.
