Trait IoBase 

pub trait IoBase<'a>: Copy {
    type Backend: IoBackend;
    type Target: ?Sized + KnownSize;

    // Required method
    fn as_view(self) -> <Self::Backend as IoBackend>::View<'a, Self::Target>;
}

Types implementing this trait (e.g. MMIO BARs or PCI config regions) can perform I/O operations on regions of memory.

This trait defines which backend shall be used for I/O operations and provides a method to convert into IoBackend::View. Users should use the Io trait which provides the actual methods to perform I/O operations.

This should be implemented on cheaply copyable handles, such as references or view types.

Required Associated Types

type Backend: IoBackend

Type that defines all I/O operations.

type Target: ?Sized + KnownSize

Type of this I/O region. For untyped regions, Region can be used.

Required Methods

fn as_view(self) -> <Self::Backend as IoBackend>::View<'a, Self::Target>

Return a view that covers the full region.

Dyn Compatibility

This trait is not dyn compatible.

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