Struct Bar

pub struct Bar<const SIZE: usize = 0> { /* private fields */ }

A PCI BAR to perform I/O-Operations on.

Invariants

Bar always holds an IoRaw inststance that holds a valid pointer to the start of the I/O memory mapped PCI bar and its size.

Methods from Deref<Target = Io<SIZE>>

pub fn addr(&self) -> usize

Returns the base address of this mapping.

pub fn maxsize(&self) -> usize

Returns the maximum size of this mapping.

pub fn readb(&self, offset: usize) -> u8
