Struct legion::storage::ComponentWriter[][src]

pub struct ComponentWriter<'a, T: Component> { /* fields omitted */ }
Expand description

Provides the ability to append new components to the entities in an archetype.

Implementations

Writes the given components into the component storage.

Safety

ptr must point to a valid array of T of length at least as long as len. The data in this array will be memcopied into the world’s internal storage. If the component type is not Copy, then the caller must ensure that the memory copied is not accessed until it is re-initialized. It is recommended to immediately std::mem::forget the source after calling extend_memcopy.

Ensures that the given spare capacity is available in the target storage location. Calling this function before calling extend_memcopy is not required, but may avoid additional vector resizes.
