Struct CapabilitiesRepr

Source 
#[repr(C)]
pub struct CapabilitiesRepr<const N: usize> { /* private fields */ }
Expand description

N must be a multiple of 4, and padded with zeros, so the whole descriptor is aligned to a 4-byte boundary.

This structure can be used to emit an ELF note section containing a list of capabilities. N must be a multiple of 4 (padded with CAP_PADDING). You can define the capabilities of a task image like so:

#[used]
#[link_section = ".caps"]
pub static mut CAPS: CapabilitiesRepr<4> = CapabilitiesRepr::new([CAP_EARLY_LOGGING,
CAP_GET_FRAMEBUFFER, CAP_PADDING, CAP_PADDING]);

impl<T> Downcast for T
where T: Any,

Source§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
Source§

fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>

Convert Rc<Trait> (where Trait: Downcast) to Rc<dyn Any>. Rc<dyn Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait.
Source§

fn as_any(&self) -> &(dyn Any + 'static)

Convert &Trait (where Trait: Downcast) to &Anydyn Any. This is needed since Rust cannot generate &Anydyn Any’s vtable from &Trait’s.
Source§

fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)

Convert &mut Trait (where Trait: Downcast) to &Anydyn Any. This is needed since Rust cannot generate &mut dyn Any’s vtable from &mut Trait’s.

where T: Any + Send + Sync,

Source§

fn into_any_arc(self: Arc<T>) -> Arc<dyn Any + Sync + Send>
