Expand description

Represents a group of components. Used for specifying which component types should be matched in query’s.

Associated Types

Associated Constants

The descriptor which exactly specifies all components of the component group.

Required methods

Returns the sorted pointers given a reference to self.

Returns an instance of self, read from the sorted pointers.

Returns a reference tuple of component types given an array of sorted pointers.

Returns a mutable reference tuple of component types given an array of sorted pointers.

Returns a tuple of slices extracted from the given pointers.

Safety:
  • The pointers must be sorted.

Returns a tuple of mutable slices extracted from the given pointers.

Safety:
  • The pointers must be sorted.

Returns an tuple of empty slices.

Returns an tuple of empty mutable slices.
