RawSharedDictEncoding

Enum RawSharedDictEncoding 

Source
pub enum RawSharedDictEncoding<'a> {
    Plain(RawPlainData<'a>),
    FsstPlain(RawFsstData<'a>),
}
Expand description

Raw encoding payload for a SharedDict column.

Unlike RawStringsEncoding, shared dictionaries do NOT have their own offset stream. Instead, each child column has its own offset stream that references the shared dictionary. This is why only Plain and FsstPlain variants exist here.

Variants§

§

Plain(RawPlainData<'a>)

Plain shared dict (2 streams): lengths + data.

§

FsstPlain(RawFsstData<'a>)

FSST plain shared dict (4 streams): symbol lengths, symbol table, lengths, corpus.

Implementations§
