Struct vortex::array::PrimitiveArray

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

Implementations

impl PrimitiveArray

pub fn patch(self, patches: Patches) -> Result<PrimitiveArray, VortexError>

impl PrimitiveArray

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

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 PrimitiveArray

pub fn new(buffer: Buffer, ptype: PType, validity: Validity) -> PrimitiveArray

pub fn from_vec<T>(values: Vec<T>, validity: Validity) -> PrimitiveArray

where T: NativePType,

pub fn from_nullable_vec<T>(values: Vec<Option<T>>) -> PrimitiveArray

where T: NativePType,

pub fn validity(&self) -> Validity

pub fn buffer(&self) -> &Buffer

pub fn maybe_null_slice<T>(&self) -> &[T]

where T: NativePType,

pub fn into_maybe_null_slice<T>(self) -> Vec<T>

where T: NativePType + ArrowNativeType,

Convert the array into a mutable vec of the given type. If possible, this will be zero-copy.

pub fn get_as_cast<T>(&self, idx: usize) -> T

where T: NativePType,

pub fn reinterpret_cast(&self, ptype: PType) -> PrimitiveArray

pub fn into_buffer(self) -> Buffer
