Enum rocks::table::EncodingType

#[repr(u8)]pub enum EncodingType {
    Plain,
    Prefix,
}

Variants

Plain

Always write full keys without any special encoding.

Prefix

Find opportunity to write the same prefix once for multiple rows. In some cases, when a key follows a previous key with the same prefix, instead of writing out the full key, it just writes out the size of the shared prefix, as well as other bytes, to save some bytes.

When using this option, the user is required to use the same prefix extractor to make sure the same prefix will be extracted from the same key. The Name() value of the prefix extractor will be stored in the file. When reopening the file, the name of the options.prefix_extractor given will be bitwise compared to the prefix extractors stored in the file. An error will be returned if the two don't match.
