Topic message records.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

consensus_timestamp: OffsetDateTime

The consensus timestamp of the message.

If there are multiple chunks, this is taken from the last chunk.

contents: Vec<u8>

The content of the message.

running_hash: Vec<u8>

The new running hash of the topic that received the message.

If there are multiple chunks, this is taken from the last chunk.

running_hash_version: u64

Version of the SHA-384 digest used to update the running hash.

If there are multiple chunks, this is taken from the last chunk.

sequence_number: u64

The sequence number of the message relative to all other messages for the same topic.

If there are multiple chunks, this is taken from the last chunk.

chunks: Option<Vec<TopicMessageChunk>>

The chunks that make up this message.

transaction: Option<TransactionId>

The TransactionId of the first chunk, gets copied to every subsequent chunk in the message.
