Crate re_viewer::external::re_chunk

A chunk of Rerun data, encoded using Arrow. Used for logging, transport, storage and compute.

Feature flags

• serde — Enable (de)serialization using serde.
• arrow — Enable conversion to and from arrow-rs types

Modules

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
• ComponentName
  The fully-qualified name of a Component, e.g. rerun.components.Position2D.
• EntityPath
  The unique identifier of an entity, e.g. camera/3/points
• 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.
• TimeInt
  A 64-bit number describing either nanoseconds, sequence numbers or fully static data.
• TimePoint
  A point in time on any number of Timelines.
• Timeline
  A time frame/space, e.g. log_time or frame_nr, coupled with the type of time it keeps.
• TimelineName
  The name of a timeline. Often something like "log_time" or "frame_nr".
• 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.

Traits

• ArrowArray
  A trait representing an immutable Arrow array. Arrow arrays are trait objects that are infallibly downcasted to concrete types according to the Array::data_type.

Type Aliases

• ChunkBatcherResult
• ChunkResult
• ChunkShared
  A simple type alias for an Arc<Chunk>.
