Struct pci_driver::regions::structured::PciBitReadClear

pub struct PciBitReadClear<'a, T: PciRegisterValue> { /* private fields */ }

A read-clear (RW1C in the spec) single bit that is part of a PCI register.

Implementations

impl<'a, T: PciRegisterValue> PciBitReadClear<'a, T>

pub fn backed_by( region: &'a dyn PciRegion, offset: u64, mask: T, write_mask: T ) -> Self

pub fn read(&self) -> Result<bool>

Read the bit.

This reads the entire register and then checks the bit we’re interested in.

pub fn clear(&self) -> Result<()>

Clear the bit (i.e., set it to 0).

This makes sure to not affect any other bits in the underlying register.

Trait Implementations

impl<'a, T: Clone + PciRegisterValue> Clone for PciBitReadClear<'a, T>

fn clone(&self) -> PciBitReadClear<'a, T>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T: PciRegisterValue> Debug for PciBitReadClear<'_, T>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
