Struct Filter 

pub struct Filter<'a, O: Operator + 'a> { /* private fields */ }

Filters rows in each chunk where column_name == predicate_value.

Implementations

impl<'a, O: Operator> Filter<'a, O>

pub fn new(inner: &'a mut O, column_name: &str, value: Value) -> Self

Construct a filter: column_name == value.

pub fn contains(inner: &'a mut O, column_name: &str, substr: &str) -> Self

Construct a CONTAINS filter.

pub fn gt(inner: &'a mut O, column_name: &str, val: i64) -> Self

Construct a greater-than filter (int64).

Trait Implementations

impl<'a, O: Operator> Operator for Filter<'a, O>

fn next_chunk(&mut self) -> Result<Option<FactorizedChunk>>

fn collect_all(&mut self) -> Result<Vec<FactorizedChunk>>

Drain all chunks and materialize as a Vec.
