SegmentBlocksBuilder

Struct SegmentBlocksBuilder 

Source
pub struct SegmentBlocksBuilder { /* private fields */ }
Expand description

Builds one segment’s blocks from rows fed in ascending row-key order.

Implementations§

Source§

impl SegmentBlocksBuilder

Source

pub fn new(target_block_bytes: NonZeroUsize) -> Self

Creates a builder that closes a data block after reaching the target decoded byte size.

Source

pub fn push<R: Serialize>( &mut self, row_key: &str, filter_key: &str, row: &R, ) -> Result<(), SstBlockCodecError>

Appends one row. filter_key is the lookup prefix point reads will probe for this row; the caller derives it per family. The row is any CBOR payload; a segment must hold one row type throughout, named by the descriptor family that references it.

Source

pub fn finish(self) -> Result<BuiltSegmentBlocks, SstBlockCodecError>

Encodes the remaining rows and assembles the object bytes.
