Structs

• Chunk
  Dense arrow-based storage of N rows of multi-component multi-temporal data for a specific entity.
• ChunkBatcher
  Implements an asynchronous batcher that coalesces PendingRows into Chunks based upon the thresholds defined in the associated ChunkBatcherConfig.
• ChunkBatcherConfig
  Defines the different thresholds of the associated ChunkBatcher.
• ChunkBuilder
  Helper to incrementally build a Chunk.
• ChunkComponentIter
  The actual iterator implementation for Chunk::iter_component.
• ChunkComponentIterItem
  The underlying item type for ChunkComponentIter.
• ChunkId
  A unique ID for a crate::Chunk.
• ChunkIndicesIter
• LatestAtQuery
  A query at a given time, for a given timeline.
• PendingRow
  A single row’s worth of data (i.e. a single log call).
• RangeQuery
  A query over a time range, for a given timeline.
• RangeQueryOptions
• RowId
  A unique ID for a row’s worth of data within a chunk.
• TimeColumn
• TimeColumnBuilder
  Helper to incrementally build a TimeColumn.
• TransportChunk
  A Chunk that is ready for transport. Obtained by calling Chunk::to_transport.
• UnitChunkShared
  A ChunkShared that is guaranteed to always contain a single row’s worth of data.

Enums

• ChunkBatcherError
  Errors that can occur when creating/manipulating a ChunkBatcher.
• ChunkError
  Errors that can occur when creating/manipulating a Chunks, directly or indirectly through the use of a crate::ChunkBatcher.

Type Aliases
