Required Methods§

Source

fn decompress(&self, data: LanceBuffer, num_values: u64) -> Result<DataBlock>

Decompress one or more values

Source

fn bits_per_value(&self) -> u64

The number of bits in each value

Returns 0 if the data type is variable-width

Currently (and probably long term) this must be a multiple of 8
