Trait IoCapable

pub trait IoCapable<T> {
    // Required methods
    unsafe fn io_read(&self, address: usize) -> T;
    unsafe fn io_write(&self, value: T, address: usize);
}

Trait indicating that an I/O backend supports operations of a certain type and providing an implementation for these operations.

Different I/O backends can implement this trait to expose only the operations they support.

For example, a PCI configuration space may implement IoCapable<u8>, IoCapable<u16>, and IoCapable<u32>, but not IoCapable<u64>, while an MMIO region on a 64-bit system might implement all four.

Required Methods

unsafe fn io_read(&self, address: usize) -> T

Performs an I/O read of type T at address and returns the result.

Safety

The range [address..address + size_of::<T>()] must be within the bounds of Self.

unsafe fn io_write(&self, value: T, address: usize)

Performs an I/O write of value at address.

Safety

The range [address..address + size_of::<T>()] must be within the bounds of Self.
