Struct datafusion_physical_expr::binary_map::ArrowBytesSet

impl<O: OffsetSizeTrait> ArrowBytesSet<O>

pub fn new(output_type: OutputType) -> Self

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

Inserts each value from values into the set

pub fn into_state(self) -> ArrayRef

Converts this set into a StringArray/LargeStringArray or BinaryArray/LargeBinaryArray 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
