Expand description

The index stored within VersionedTreeRoot::by_sequence_root.

Fields

key: ArcBytes<'static>

The key associated with this sequence id.

last_sequence: Option<SequenceId>

The previous sequence of this key.

value_length: u32

The size of the value stored on disk.

position: u64

The position of the value on disk.

embedded: Option<Embedded>

The embeded index at the time of the sequence being written. This value is always present on data written from v0.6.0 onwards. If the tree being used was created after v0.6.0 or has had compaction run on v0.6.0, it is safe to unwrap this value.
