Struct sstable::TableBuilder

pub struct TableBuilder<Dst: Write> { /* private fields */ }

A TableBuilder is used to create a table from a set of sorted string pairs and write it to a file or a buffer.

Implementations

impl<Dst: Write> TableBuilder<Dst>

pub fn new_no_filter(opt: Options, dst: Dst) -> TableBuilder<Dst>

impl<Dst: Write> TableBuilder<Dst>

TableBuilder is used for building a new SSTable. It groups entries into blocks, calculating checksums and bloom filters.

pub fn new(opt: Options, dst: Dst) -> TableBuilder<Dst>

Create a new table builder.

pub fn entries(&self) -> usize

Returns the current number of entries.

pub fn size_estimate(&self) -> usize

Returns the estimated size of the SSTable in bytes. It includes already written and outstanding bytes.

pub fn add(&mut self, key: &[u8], val: &[u8]) -> Result<()>

Add a key to the table. The key must be lexically greater or equal to the one that was previously added.

pub fn finish(self) -> Result<usize>
