Struct lance_encoding::decoder::FilterExpression

source ·

pub struct FilterExpression(pub Bytes);

Expand description

A filter expression to apply to the data

The core decoders do not currently take advantage of filtering in any way. In order to maintain the abstraction we represent filters as an arbitrary byte sequence.

We recommend that encodings use Substrait for filters.

Implementations§

source §

impl FilterExpression

source

pub fn no_filter() -> Self

Create a filter expression that does not filter any data

This is currently represented by an empty byte array. Encoders that are “filter aware” should make sure they handle this case.
