Struct datafusion_physical_expr_common::binary_view_map::ArrowBytesViewSet

pub struct ArrowBytesViewSet(/* private fields */);

HashSet optimized for storing string or binary values that can produce that the final set as a GenericBinaryViewArray with minimal copies.

Implementations

impl ArrowBytesViewSet

pub fn new(output_type: OutputType) -> Self

pub fn insert(&mut self, values: &ArrayRef)

Inserts each value from values into the set

pub fn take(&mut self) -> Self

Return the contents of this map and replace it with a new empty map with the same output type

pub fn into_state(self) -> ArrayRef

Converts this set into a StringViewArray or BinaryViewArray containing each distinct value that was interned. This is done without copying the values.

pub fn len(&self) -> usize

Returns the total number of distinct values (including nulls) seen so far

pub fn is_empty(&self) -> bool

pub fn non_null_len(&self) -> usize

returns the total number of distinct values (not including nulls) seen so far

pub fn size(&self) -> usize

Return the total size, in bytes, of memory used to store the data in this set, not including self
