Struct KernelStacks 

Source 
pub struct KernelStacks<M>
where
    M: KernelCallbackObject,
{ /* private fields */ }
Expand description

The kernel manages multiple call frame stacks. There will always be a single “current” stack (and call frame) in context.

impl<U> As for U

Source§

fn as_<T>(self) -> T
