Struct ArrowBytesSet

pub struct ArrowBytesSet<O>(/* private fields */)
where
    O: OffsetSizeTrait;

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

Implementations

impl<O> ArrowBytesSet<O>

where O: OffsetSizeTrait,

pub fn new(output_type: OutputType) -> ArrowBytesSet<O>

pub fn take(&mut self) -> ArrowBytesSet<O>

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

pub fn insert(&mut self, values: &Arc<dyn Array>)

Inserts each value from values into the set

pub fn into_state(self) -> Arc<dyn Array>

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

Trait Implementations

impl<O> Debug for ArrowBytesSet<O>

where O: Debug + OffsetSizeTrait,

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

Formats the value using the given formatter.
