Module stages

This module contains each stage of the derivation pipeline.

It offers a high-level API to functionally apply each stage’s output as an input to the next stage, until finally arriving at the produced execution payloads.

Stages:

1. L1 Traversal
2. L1 Retrieval
3. Frame Queue
4. Channel Provider
5. Channel Reader (Batch Decoding)
6. Batch Stream (Introduced in the Holocene Hardfork)
7. Batch Queue
8. Payload Attributes Derivation
9. (Omitted) Engine Queue

Structs

• AttributesQueue
  AttributesQueue accepts batches from the BatchQueue stage and transforms them into OpPayloadAttributes.
• BatchProvider
  The BatchProvider stage is a mux between the BatchQueue and BatchValidator stages.
• BatchQueue
  BatchQueue is responsible for o rdering unordered batches and gnerating empty batches when the sequence window has passed.
• BatchStream
  BatchStream stage in the derivation pipeline.
• BatchValidator
  The BatchValidator stage is responsible for validating the SingleBatches from the BatchStream AttributesQueue’s consumption.
• ChannelAssembler
  The ChannelAssembler stage is responsible for assembling the Frames from the FrameQueue stage into a raw compressed Channel.
• ChannelBank
  ChannelBank is a stateful stage that does the following:
• ChannelProvider
  The ChannelProvider stage is a mux between the ChannelBank and ChannelAssembler stages.
• ChannelReader
  ChannelReader is a stateful stage that reads Batches from Channels.
• FrameQueue
  The FrameQueue stage of the derivation pipeline. This stage takes the output of the L1Retrieval stage and parses it into frames.
• L1Retrieval
  The L1Retrieval stage of the derivation pipeline.
• L1Traversal
  The L1Traversal stage of the derivation pipeline.

Traits

• BatchStreamProvider
  Provides Batches for the BatchStream stage.
• ChannelReaderProvider
  The ChannelReader provider trait.
• FrameQueueProvider
  Provides data frames for the FrameQueue stage.
• L1RetrievalProvider
  Provides L1 blocks for the L1Retrieval stage. This is the previous stage in the pipeline.
• NextBatchProvider
  Provides Batches for the BatchQueue and BatchValidator stages.
• NextFrameProvider
  Provides frames for the ChannelBank and ChannelAssembler stages.

Functions

• decompress_brotli
  Decompresses the given bytes data using the Brotli decompressor implemented in the brotli crate.
