Struct HeapNullBitmap

#[repr(transparent)]
pub struct HeapNullBitmap {
    inner: FixedBitSet,
}

Null bitmap on heap. We use this for the edge case where group key sizes are larger than 64. This is because group key null bits cannot fit into a u64 on the stack if they exceed 64 bits. NOTE(kwannoel): This is not really optimized as it is an edge case.

Fields

inner: FixedBitSet

Implementations

impl HeapNullBitmap

fn with_capacity(n: usize) -> Self

Trait Implementations

impl Clone for HeapNullBitmap

fn clone(&self) -> HeapNullBitmap

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HeapNullBitmap

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

Formats the value using the given formatter.

impl EstimateSize for HeapNullBitmap

fn estimated_heap_size(&self) -> usize

The estimated heap size of the current struct in bytes.

fn estimated_size(&self) -> usize

where Self: Sized,

The estimated total size of the current struct in bytes, including the estimated_heap_size and the size of Self.

impl<T: AsRef<[bool]> + IntoIterator<Item = bool>> From<T> for HeapNullBitmap

fn from(value: T) -> Self

Converts to this type from the input type.

impl NullBitmap for HeapNullBitmap

fn empty() -> Self

fn is_empty(&self) -> bool

fn set_true(&mut self, idx: usize)

fn contains(&self, x: usize) -> bool

fn is_subset(&self, other: &Self) -> bool

fn from_bool_vec<T: AsRef<[bool]> + IntoIterator<Item = bool>>(value: T) -> Self

impl PartialEq for HeapNullBitmap

fn eq(&self, other: &HeapNullBitmap) -> 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.
