Represents an object that provides PIO manager operations.

Required Associated Types

type D: DevicePio

Type of the objects that can be registered with this PioManager.

Required Methods

fn pio_device(&self, addr: PioAddress) -> Option<(&PioRange, &Self::D)>

Return a reference to the device registered at addr, together with the associated range, if available.

fn pio_read(&self, addr: PioAddress, data: &mut [u8]) -> Result<(), Error>

Dispatch a read operation to the device registered at addr.

fn pio_write(&self, addr: PioAddress, data: &[u8]) -> Result<(), Error>

Dispatch a write operation to the device registered at addr.

fn register_pio( &mut self, range: PioRange, device: Self::D, ) -> Result<(), Error>

Register the provided device with the specified range.

fn deregister_pio(&mut self, addr: PioAddress) -> Option<(PioRange, Self::D)>

Deregister the device currently registered at addr together with the associated range.

Dyn Compatibility

This trait is dyn compatible.

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