Struct legion::storage::UnknownComponentWriter [−][src]
pub struct UnknownComponentWriter<'a> { /* 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 the correct component type 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.
