Trait IoCapable 

Source 
pub trait IoCapable<T>: IoBackend {
    // Required methods
    fn io_read<'a>(view: Self::View<'a, T>) -> T;
    fn io_write<'a>(view: Self::View<'a, T>, value: T);
}
Expand description

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§

Source

fn io_read<'a>(view: Self::View<'a, T>) -> T

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

Source

fn io_write<'a>(view: Self::View<'a, T>, value: T)

Performs an I/O write of value at view.

Dyn Compatibility§

This trait is not dyn compatible.

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