pub struct WriteOnly<T: Copy>(_);

A volatile wrapper which only allows write operations.

The size of this struct is the same as the contained type.

Implementations

impl<T: Copy> WriteOnly<T>

pub fn new(value: T) -> WriteOnly<T>

Constructs a new write only volatile wrapper around the given value.

use volatile::WriteOnly;

let value = WriteOnly::new(0u32);

Panics

This function never panics.

pub fn write(&mut self, value: T)

Performs a volatile write of value value into the contained value. Functionally identical to Volatile::write.

use volatile::WriteOnly;

let mut value = WriteOnly::new(0u32);

value.write(42u32);
