Structs

• BatchReader
  Batch Reader provides a function that iteratively consumes batches from the reader. The L1Inclusion block is also provided at creation time. Warning: the batch reader can read every batch-type. The caller of the batch-reader should filter the results.
• BatchTransaction
  BatchTransaction is a set of Frames that can be Into::into Bytes. if the size exceeds the desired threshold.
• BatchWithInclusionBlock
  A batch with its inclusion block.
• BlockInfo
  Block Header Info
• BrotliCompressor
  The brotli compressor.
• Channel
  A Channel is a set of batches that are split into at least one, but possibly multiple frames.
• ChannelOut
  ChannelOut constructs a channel from compressed, encoded batch data.
• Config
  Configuration for the compressor itself.
• ExecutingMessage
  Solidity event, emitted when a cross chain message is being executed.
• Frame
  A channel frame is a segment of a channel’s data.
• FrameIter
  An iterator over encoded frames.
• L1BlockInfoBedrock
  Represents the fields within a Bedrock L1 block info transaction.
• L1BlockInfoEcotone
  Represents the fields within an Ecotone L1 block info transaction.
• L1InfoDepositSource
  A L1 info deposit transaction source.
• L2BlockInfo
  L2 Block Header Info
• MessageIdentifier
  A MessageIdentifier uniquely represents a log that is emitted from a chain within the broader dependency set. It is included in the calldata of a transaction sent to the CrossL2Inbox contract.
• MessagePayload
  A MessagePayload is the raw payload of an initiating message.
• RatioCompressor
  Ratio Compressor
• RawSpanBatch
  Raw Span Batch
• ShadowCompressor
  Shadow Compressor
• SingleBatch
  Represents a single batch: a single encoded L2 block

  The span batch contains the input to build a span of L2 blocks in derived form.
• SpanBatchBits
  Type for span batch bits.
• SpanBatchEip1559TransactionData
  The transaction data for an EIP-1559 transaction within a span batch.
• SpanBatchEip2930TransactionData
  The transaction data for an EIP-2930 transaction within a span batch.
• SpanBatchElement
  A single batch element is similar to the SingleBatch type but does not contain the parent hash and epoch hash since spans do not contain this data for every block in the span.
• SpanBatchLegacyTransactionData
  The transaction data for a legacy transaction within a span batch.
• SpanBatchPayload
  Span Batch Payload
• SpanBatchPrefix
  Span Batch Prefix
• SpanBatchTransactions
  This struct contains the decoded information for transactions in a span batch.
• UpgradeDepositSource
  An upgrade deposit transaction source.
• UserDepositSource
  A deposit transaction source.
• ZlibCompressor
  The ZLIB compressor.
