Struct vortex_array::array::VarBinArray

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

Implementations

impl VarBinArray

pub fn maybe_from(data: impl AsRef<ArrayData>) -> Option<Self>

Optionally downcast an ArrayData instance to a specific encoding.

Preferred in cases where a backtrace isn’t needed, like when trying multiple encoding to go down different code paths.

impl VarBinArray

pub fn try_new( offsets: ArrayData, bytes: ArrayData, dtype: DType, validity: Validity, ) -> VortexResult<Self>

pub fn offsets(&self) -> ArrayData

pub fn first_offset<T: NativePType + for<'a> TryFrom<&'a Scalar, Error = VortexError>>( &self, ) -> VortexResult<T>

pub fn bytes(&self) -> ArrayData

Access the value bytes child array

Note

Bytes child array is never sliced when the array is sliced so this can include values that are not logically present in the array. Users should prefer sliced_bytes unless they’re resolving values via offset child array.

pub fn validity(&self) -> Validity

pub fn sliced_bytes(&self) -> VortexResult<ArrayData>

Access value bytes child array limited to values that are logically present in the array unlike bytes.

pub fn from_vec<T: AsRef<[u8]>>(vec: Vec<T>, dtype: DType) -> Self

pub fn from_iter<T: AsRef<[u8]>, I: IntoIterator<Item = Option<T>>>( iter: I, dtype: DType, ) -> Self

pub fn from_iter_nonnull<T: AsRef<[u8]>, I: IntoIterator<Item = T>>( iter: I, dtype: DType, ) -> Self

pub fn offset_at(&self, index: usize) -> usize

pub fn bytes_at(&self, index: usize) -> VortexResult<Buffer>

pub fn into_parts(self) -> (DType, ArrayData, ArrayData, Validity)

Consumes self, returning a tuple containing the DType, the bytes array, the offsets array, and the validity.

fn with_iterator<F, R>(&self, f: F) -> VortexResult<R>

where F: for<'a> FnOnce(&mut dyn Iterator<Item = Option<&'a [u8]>>) -> R,
