Struct legion::storage::UnknownComponentWriter
source · [−]pub struct UnknownComponentWriter<'a> { /* private fields */ }
Expand description
Provides the ability to append new components to the entities in an archetype.
Implementations
sourceimpl<'a> UnknownComponentWriter<'a>
impl<'a> UnknownComponentWriter<'a>
sourcepub unsafe fn extend_memcopy_raw(&mut self, ptr: *const u8, len: usize)
pub unsafe fn extend_memcopy_raw(&mut self, ptr: *const u8, len: usize)
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
.
sourcepub fn ensure_capacity(&mut self, space: usize)
pub fn ensure_capacity(&mut self, space: usize)
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.
sourcepub fn move_archetype_from(
&mut self,
src_archetype: ArchetypeIndex,
src: &mut dyn UnknownComponentStorage
)
pub fn move_archetype_from(
&mut self,
src_archetype: ArchetypeIndex,
src: &mut dyn UnknownComponentStorage
)
Moves all of the components from the given storage location into this writer’s storage.
sourcepub fn move_component_from(
&mut self,
src_archetype: ArchetypeIndex,
src_component: ComponentIndex,
src: &mut dyn UnknownComponentStorage
)
pub fn move_component_from(
&mut self,
src_archetype: ArchetypeIndex,
src_component: ComponentIndex,
src: &mut dyn UnknownComponentStorage
)
Moves a single component from the given storage location into this writer’s storage.
