Trait UnsafeWriteReg 

pub trait UnsafeWriteReg<Layout> {
    // Required method
    unsafe fn write(&self, value: Layout);

    // Provided method
    unsafe fn modify<ModifyFn, Ret>(&self, cb: ModifyFn) -> Ret
       where ModifyFn: FnOnce(&mut Layout) -> Ret,
             Self: ReadReg<Layout> { ... }
}

A trait representing an unsafe-writable register.

Required Methods

unsafe fn write(&self, value: Layout)

Safety

The caller must guarantee that the write does not result in undefined behaviour.

Provided Methods

unsafe fn modify<ModifyFn, Ret>(&self, cb: ModifyFn) -> Ret

where ModifyFn: FnOnce(&mut Layout) -> Ret, Self: ReadReg<Layout>,

Safety

The caller must guarantee that the write does not result in undefined behaviour.

Dyn Compatibility

This trait is not dyn compatible.

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