Trait ToLayoutOptional 

pub(crate) trait ToLayoutOptional<'dom, T: DomObject> {
    // Required method
    unsafe fn to_layout(&self) -> Option<LayoutDom<'dom, T>>;
}

Required Methods

unsafe fn to_layout(&self) -> Option<LayoutDom<'dom, T>>

Retrieve a copy of the inner optional Dom<T> as LayoutDom<T>. For use by layout, which can’t use safe types like Temporary.

Safety

The return value holds a Rust reference to the underlying data, which should be safe as long as unsafe is not used to override the lifetime in some way.

• The caller must not modify the underlying DOM object via non-layout handles.
• The caller must ensure that garbage collection does not occur while the LayoutDom handle is alive.
