Trait UserModeHooks 

pub trait UserModeHooks {
    // Provided methods
    fn has_kernel_event(&self) -> bool { ... }
    fn pre_user_run(&self, _guard: &DisabledLocalIrqGuard) { ... }
}

Hooks that will be called during UserMode::execute.

Provided Methods

fn has_kernel_event(&self) -> bool

Checks whether a kernel event is pending.

This method will be called after user space is interrupted by external interrupts. If the result is true, UserMode::execute will return with ReturnReason::KernelEvent.

fn pre_user_run(&self, _guard: &DisabledLocalIrqGuard)

Prepares user space execution.

This method will be called just before entering user space. Local IRQs are disabled and will only be enabled after entering user space.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
