Struct NullableDataBlock 

pub struct NullableDataBlock {
    pub data: Box<DataBlock>,
    pub nulls: LanceBuffer,
    pub block_info: BlockInfo,
}

Wraps a data block and adds nullability information to it

Note: this data block should not be used for future work. It will be deprecated in the 2.1 version of the format where nullability will be handled by the structural encoders.

Fields

data: Box<DataBlock>

The underlying data

nulls: LanceBuffer

A bitmap of validity for each value

block_info: BlockInfo
