Cast kernels to convert ArrayRef
between supported datatypes.
See cast_with_options
for more information on specific conversions.
Example:
// int32 to float64
let a = Int32Array::from(vec![5, 6, 7]);
let b = cast(&a, &DataType::Float64).unwrap();
let c = b.as_primitive::<Float64Type>();
assert_eq!(5.0, c.value(0));
assert_eq!(6.0, c.value(1));
assert_eq!(7.0, c.value(2));
Structs§
- CastOptions provides a way to override the default cast behaviors
Functions§
- Return true if a value of type
from_type
can be cast into a value ofto_type
. - Cast
array
to the provided data type and return a new Array with typeto_type
, if possible. - Try to cast
array
toto_type
if possible.
