Traits

Io

Extension trait to provide I/O operation methods to types that implement IoBase.

IoBackend

I/O backends.

IoBase

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

IoCapable

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

IoCopyable

Trait indicating that an I/O backend supports memory copy operations.

IoLoc

Describes a given I/O location: its offset, width, and type to convert the raw value from and into.

Type Aliases

PhysAddr

Physical address type.

ResourceSize
