Enum RawSharedDictEncoding 

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

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

impl<'a> RawSharedDictEncoding<'a>

pub fn plain(plain_data: RawPlainData<'a>) -> Self

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

pub fn fsst_plain(fsst_data: RawFsstData<'a>) -> Self

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

pub fn dict_streams(&self) -> Vec<&RawStream<'_>>

Dict streams in wire order (for serialization).

Trait Implementations

impl<'a> Clone for RawSharedDictEncoding<'a>

fn clone(&self) -> RawSharedDictEncoding<'a>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for RawSharedDictEncoding<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> PartialEq for RawSharedDictEncoding<'a>

fn eq(&self, other: &RawSharedDictEncoding<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
