Struct pci_driver::regions::structured::PciBitsReadOnly

pub struct PciBitsReadOnly<'a, T, U>where
    T: PciRegisterValue + TryInto<U>,
    T::Error: Debug,
    U: PciRegisterValue,{ /* private fields */ }

A read-only sequence of bits that is part of a PCI register.

Implementations

impl<'a, T, U> PciBitsReadOnly<'a, T, U>where T: PciRegisterValue + TryInto<U>, T::Error: Debug, U: PciRegisterValue,

pub fn backed_by( region: &'a dyn PciRegion, offset: u64, mask: T, shift: u8 ) -> Self

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

Read the bit sequence.

This reads the entire register and then masks and shifts the part we’re interested in.

Trait Implementations

impl<'a, T, U> Clone for PciBitsReadOnly<'a, T, U>where T: PciRegisterValue + TryInto<U> + Clone, T::Error: Debug, U: PciRegisterValue + Clone,

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

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<T, U> Debug for PciBitsReadOnly<'_, T, U>where T: PciRegisterValue + TryInto<U>, T::Error: Debug, U: PciRegisterValue,

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

Formats the value using the given formatter.

impl<'a, T, U> Copy for PciBitsReadOnly<'a, T, U>where T: PciRegisterValue + TryInto<U> + Copy, T::Error: Debug, U: PciRegisterValue + Copy,
