Struct commitlog::Message

pub struct Message<'a> { /* fields omitted */ }

Messages contain finite-sized binary values with an offset from the beginning of the log.

Bytes	Encoding	Value
0-7	Little Endian u64	Offset
8-11	Little Endian u32	Payload Size
12-19	Little Endian u64	SeaHash
20+		Payload

Seahash is chosen because of its performance and quality. It is seeded with the following constants: 0x16f11fe89b0d677c, 0xb480a793d8e6c86c, 0x6fe2e5aaf078ebc9, 0x14f994a4c5259381
