Enum IndexOutput

pub enum IndexOutput {
    Reference(Range<u64>),
    Owned(Box<[u8]>),
    Remove(Box<[u8]>),
    RemovePrefix(Box<[u8]>),
}

Output of an index function. Bytes that can be used for lookups.

Variants

Reference(Range<u64>)

The index key is a slice, relative to the data entry (ex. input of the index function).

Use this if possible. It generates smaller indexes.

Owned(Box<[u8]>)

The index key is a separate sequence of bytes unrelated to the input bytes.

Use this if the index key is not in the entry. For example, if the entry is compressed.

Remove(Box<[u8]>)

Remove all values associated with the key in the index.

This only affects the index. The entry is not removed in the log.

RemovePrefix(Box<[u8]>)

Remove all values associated with all keys with the given prefix in the index.

This only affects the index. The entry is not removed in the log.
