Struct MenuVTable 

#[repr(C)]
pub struct MenuVTable {
    pub sub_menu: unsafe fn(VRef<'_, MenuVTable>, Option<&MenuEntry>, &mut SharedVector<MenuEntry>),
    pub activate: unsafe fn(VRef<'_, MenuVTable>, &MenuEntry),

    pub dealloc: unsafe fn(_: &MenuVTable, ptr: *mut u8, layout: Layout),
}

Interface for native menu and menubar

Fields

sub_menu: unsafe fn(VRef<'_, MenuVTable>, Option<&MenuEntry>, &mut SharedVector<MenuEntry>)

Return the list of items for the sub menu (or the main menu of parent is None)

activate: unsafe fn(VRef<'_, MenuVTable>, &MenuEntry)

Handler when the menu entry is activated

drop_in_place: unsafe fn(VRefMut<'_, MenuVTable>) -> Layout

drop_in_place handler

dealloc: unsafe fn(_: &MenuVTable, ptr: *mut u8, layout: Layout)

dealloc handler

Implementations

impl MenuVTable

pub fn new<T: Menu>() -> Self

Create a vtable suitable for a given type implementing the trait.

Trait Implementations

impl HasStaticVTable<MenuVTable> for MenuFromItemTree

fn static_vtable() -> &'static MenuVTable

Safety: must be a valid VTable for Self

impl VTableMeta for MenuVTable

type VTable = MenuVTable

That’s the VTable itself (so most likely Self)

type Target = MenuTO

That’s the trait object that implements the functions

impl VTableMetaDropInPlace for MenuVTable

unsafe fn drop_in_place(vtable: &Self::VTable, ptr: *mut u8) -> Layout

Safety

unsafe fn dealloc(vtable: &Self::VTable, ptr: *mut u8, layout: Layout)

Safety
