Sets box to the precise write/read chunk template.

For the purpose of this method, only hard constraints on grid_origin() and (*this)[usage].shape() are considered; soft constraints are ignored.

For any dimension i where grid_origin().hard_constraint[i] == false or (*this)[usage].shape().hard_constraint[i] == false, box[i] is set to IndexInterval::Infinite().

Parameters:¶

Usage usage¶

Must be either kWrite or kRead.

out

MutableBoxView<> box¶

Set to the chunk template.

Error absl::StatusCode::kInvalidArgument:¶

if box.rank() != rank().

Error absl::StatusCode::kInvalidArgument:¶

if hard constraints on grid_origin and the chunk shape would lead to an invalid box.
