Enum NullableRowAddrMask 

pub enum NullableRowAddrMask {
    AllowList(NullableRowAddrSet),
    BlockList(NullableRowAddrSet),
}

A version of RowAddrMask that supports nulls.

This mask handles three-valued logic for SQL expressions, where a filter can evaluate to TRUE, FALSE, or NULL. The selected set includes rows that are TRUE or NULL. The nulls set includes rows that are NULL.

Variants

AllowList(NullableRowAddrSet)

BlockList(NullableRowAddrSet)

Implementations

impl NullableRowAddrMask

pub fn allow_nothing() -> Self

A mask that matches no rows (TRUE = ∅, NULL = ∅).

pub fn all_rows() -> Self

A mask that matches every row (TRUE = universe, NULL = ∅).

pub fn selected(&self, row_id: u64) -> bool

pub fn drop_nulls(self) -> RowAddrMask

Trait Implementations

impl BitAnd for NullableRowAddrMask

type Output = NullableRowAddrMask

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self::Output

Performs the & operation.

impl BitOr for NullableRowAddrMask

type Output = NullableRowAddrMask

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl Clone for NullableRowAddrMask

fn clone(&self) -> NullableRowAddrMask

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NullableRowAddrMask

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Not for NullableRowAddrMask

type Output = NullableRowAddrMask

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl PartialEq for NullableRowAddrMask

fn eq(&self, other: &NullableRowAddrMask) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
