Enum RowIdSequence

pub enum RowIdSequence {
    InlineRowIds(Vec<u8>),
    ExternalRowIds(ExternalFile),
}

A serialized RowIdSequence message (see rowids.proto).

These are the row ids for the fragment, in order of the rows as they appear. That is, if a fragment has 3 rows, and the row ids are [1, 42, 3], then the first row is row 1, the second row is row 42, and the third row is row 3.

Variants

InlineRowIds(Vec<u8>)

If small (< 200KB), the row ids are stored inline.

ExternalRowIds(ExternalFile)

Otherwise, stored as part of a file.

Implementations

impl RowIdSequence

pub fn encode(&self, buf: &mut impl BufMut)

Encodes the message to a buffer.

pub fn merge( field: &mut Option<RowIdSequence>, tag: u32, wire_type: WireType, buf: &mut impl Buf, ctx: DecodeContext, ) -> Result<(), DecodeError>

Decodes an instance of the message from a buffer, and merges it into self.

pub fn encoded_len(&self) -> usize

Returns the encoded length of the message without a length delimiter.

Trait Implementations

impl Clone for RowIdSequence

fn clone(&self) -> RowIdSequence

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for RowIdSequence

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

Formats the value using the given formatter.

impl PartialEq for RowIdSequence

fn eq(&self, other: &RowIdSequence) -> 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.

impl TryFrom<RowIdSequence> for RowIdMeta

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: RowIdSequence) -> Result<Self>

Performs the conversion.
