ArrowArray C Data Interface: array (columnar data).

See: https://arrow.apache.org/docs/format/CDataInterface.html#the-arrowarray-structure

Ownership: This type has no Drop impl. Callers must invoke the release callback (if Some) before dropping to free resources.

Implementations

impl ArrowArray

pub fn empty() -> Self

Create an empty (released) array.

pub fn is_released(&self) -> bool

Whether this array has been released (release callback is None).

pub unsafe fn from_raw<T>(ptr: &T) -> &Self

Borrow a foreign C Data Interface array as ours (zero-copy).

Safety

T must have the Arrow C Data Interface ArrowArray memory layout.

pub unsafe fn from_raw_mut<T>(ptr: &mut T) -> &mut Self

Mutably borrow a foreign C Data Interface array as ours (zero-copy).

Safety

T must have the Arrow C Data Interface ArrowArray memory layout.

pub unsafe fn as_raw<T>(&self) -> &T

Borrow ours as a foreign C Data Interface array type (zero-copy).

Safety

T must have the Arrow C Data Interface ArrowArray memory layout.

pub unsafe fn from_owned<T>(val: T) -> Self

Take ownership of a foreign C Data Interface array.

Safety

• T must have the Arrow C Data Interface ArrowArray memory layout.
• Ownership transfers — the caller must not use or drop the original.

pub unsafe fn into_owned<T>(self) -> T

Convert into a foreign C Data Interface array type.

Safety

• T must have the Arrow C Data Interface ArrowArray memory layout.
• Ownership transfers — the caller must not use or drop the original.
