Struct sstable::Table

pub struct Table { /* fields omitted */ }

Table is used for accessing SSTables.

Methods

impl Table

pub fn new_from_file(opt: Options, path: &Path) -> Result<Table>

Creates a new table reader from a file at path.

pub fn new(
    opt: Options,
    file: Box<dyn RandomAccess>,
    size: usize
) -> Result<Table>

Creates a new table reader.

pub fn approx_offset_of(&self, key: &[u8]) -> usize

Returns the offset of the block that contains key.

pub fn iter(&self) -> TableIterator

Returns an iterator over an SSTable. Iterators hold internal references to the table, so make sure to let them expire when not needed anymore.

pub fn get(&self, key: &[u8]) -> Result<Option<Vec<u8>>>

Retrieve an entry for a key from the table. This function uses the attached filters, so is better suited if you frequently look for non-existing values (as it will detect the non-existence of an entry in a block without having to load the block).

Trait Implementations

impl Clone for Table

fn clone(&self) -> Table

Returns a copy of the value.

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

Performs copy-assignment from source.
