Struct pci_driver::regions::structured::PciBitsReadWrite

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

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

Implementations

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

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

pub fn write(&self, value: U) -> Result<()>

Write the bit sequence.

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

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

Returns a copy of the value.

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