Implementations§
source§impl ComponentDescriptor
impl ComponentDescriptor
sourcepub unsafe fn new_with_layout(
name: impl Into<Cow<'static, str>>,
storage_type: StorageType,
layout: Layout,
drop: Option<for<'a> unsafe fn(_: OwningPtr<'a>)>
) -> Self
pub unsafe fn new_with_layout( name: impl Into<Cow<'static, str>>, storage_type: StorageType, layout: Layout, drop: Option<for<'a> unsafe fn(_: OwningPtr<'a>)> ) -> Self
Create a new ComponentDescriptor
.
Safety
- the
drop
fn must be usable on a pointer with a value of the layoutlayout
- the component type must be safe to access from any thread (Send + Sync in rust terms)
sourcepub fn new_resource<T: Resource>() -> Self
pub fn new_resource<T: Resource>() -> Self
Create a new ComponentDescriptor
for a resource.
The StorageType
for resources is always TableStorage
.
pub fn storage_type(&self) -> StorageType
pub fn type_id(&self) -> Option<TypeId>
pub fn name(&self) -> &str
