Struct Bus 

pub struct Bus<A: BusAddress, D> { /* private fields */ }

A bus that’s agnostic to the range address type and device type.

Implementations

impl<A: BusAddress, D> Bus<A, D>

pub fn new() -> Self

Create an empty bus.

pub fn device(&self, addr: A) -> Option<(&BusRange<A>, &D)>

Return the registered range and device associated with addr.

pub fn device_mut(&mut self, addr: A) -> Option<(&BusRange<A>, &mut D)>

Return the registered range and a mutable reference to the device associated with addr.

pub fn register(&mut self, range: BusRange<A>, device: D) -> Result<(), Error>

Register a device with the provided range.

pub fn deregister(&mut self, addr: A) -> Option<(BusRange<A>, D)>

Deregister the device associated with addr.

pub fn check_access( &self, addr: A, len: usize, ) -> Result<(&BusRange<A>, &D), Error>

Verify whether an access starting at addr with length len fits within any of the registered ranges. Return the range and a handle to the device when present.

Trait Implementations

impl<A: BusAddress, D> Default for Bus<A, D>

fn default() -> Self

Returns the “default value” for a type.
