Ergonomics: Allow use of an ArrayRef as an &dyn Array
Returns a reference-counted pointer to the underlying data of this array.
Returns a zero-copy slice of this array with the indicated offset and length. Read more
Returns the offset into the underlying data used by this array(-slice).
Note that the underlying data can be shared by many arrays.
This defaults to 0
. Read more
Returns whether the element at index
is null.
When using this function on a slice, the index is relative to the slice. Read more
Returns whether the element at index
is not null.
When using this function on a slice, the index is relative to the slice. Read more
Returns the total number of null values in this array. Read more
Returns the total number of bytes of memory pointed to by this array. The buffers store bytes in the Arrow memory format, and include the data as well as the validity map. Read more
Returns the total number of bytes of memory occupied physically by this array.
This value will always be greater than returned by get_buffer_memory_size()
and
includes the overhead of the data structures that contain the pointers to the various buffers. Read more
returns two pointers that represent this array in the C Data Interface (FFI)
