Struct sstable::table_builder::TableBuilder

pub struct TableBuilder<C: Comparator, Dst: Write> { /* fields omitted */ }

A table consists of DATA BLOCKs, an INDEX BLOCK and a FOOTER.

DATA BLOCKs, INDEX BLOCK BLOCK are built using the code in the block module.

The footer is a pointer pointing to the index block, padding to fill up to 40 B and at the end the 8B magic number 0xdb4775248b80fb57.

fn new_defaults(dst: Dst) -> TableBuilder<StandardComparator, Dst>

Create a new TableBuilder with default comparator and options.

impl<C: Comparator, Dst: Write> TableBuilder<C, Dst>

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

Create a new TableBuilder.

fn entries(&self) -> usize

Returns how many entries have been written.

fn add(&mut self, key: &[u8], val: &[u8])
