Mojo trait
CopyPolicy
The CopyPolicy trait defines requirements needed for a tensor to be copied.
These requirements check the compatibility of the source and destination tensors.

Aliases
__del__is_trivial
alias __del__is_trivial
A flag (often compiler generated) to indicate whether the implementation of __del__ is trivial.
The implementation of __del__ is considered to be trivial if:
- The struct has a compiler-generated trivial destructor and all its fields
have a trivial
__del__method.
In practice, it means that the __del__ can be considered as no-op.
Required methods
verify_source_tensor
static verify_source_tensor(src: LayoutTensor[dtype, layout, origin, address_space=address_space, element_layout=element_layout, layout_int_type=layout_int_type, linear_idx_type=linear_idx_type, masked=masked, alignment=alignment])
A static function that verifies the source tensor is compatible with the copy operation. If the tensor is not valid compilation will fail.
Args:
- src (
LayoutTensor): The source tensor that will be copied from.
verify_destination_tensor
static verify_destination_tensor(dst: LayoutTensor[dtype, layout, origin, address_space=address_space, element_layout=element_layout, layout_int_type=layout_int_type, linear_idx_type=linear_idx_type, masked=masked, alignment=alignment])
A static function that verifies the destination tensor is compatible with the copy operation. If the tensor is not valid compilation will fail.
Args:
- dst (
LayoutTensor): The destination tensor that will be copied to.
