Trait IRQHandlerEpilogue 

Source 
pub trait IRQHandlerEpilogue {
    // Required methods
    unsafe fn do_prologue();
    unsafe fn do_epilogue();

    // Provided method
    fn get_gate() -> IRQGate { ... }
}
Expand description

device driver trait with both prologue and epilogue

Required Methods§

Source

unsafe fn do_prologue()

same as in IRQHandler

Source

unsafe fn do_epilogue()

the “softirq” part of the irq handler, it allows interrupts but all epilogues must be linearized, therefore an context swap must not happen when there is a running epilogue.

Provided Methods§

Source

fn get_gate() -> IRQGate

Dyn Compatibility§

This trait is not dyn compatible.

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