Struct legion::storage::ComponentWriter [−][src]
Provides the ability to append new components to the entities in an archetype.
Implementations
impl<'a, T: Component> ComponentWriter<'a, T>
[src]
pub unsafe fn extend_memcopy(&mut self, ptr: *const T, len: usize)
[src]
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
.
pub fn ensure_capacity(&mut self, space: usize)
[src]
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.
