Struct ByteEnabledDwordRead 

pub struct ByteEnabledDwordRead<'a> { /* private fields */ }

A DWORD value with byte enables for PCI configuration space read.

Implementations

impl<'a> ByteEnabledDwordRead<'a>

pub const fn new(value: &'a mut u32, byte_enable: PciConfigByteEnable) -> Self

Create a byte-enabled DWORD value.

pub const fn with_all_bytes_enabled(value: &'a mut u32) -> Self

Create a full-DWORD value with all byte lanes enabled.

pub const fn byte_enable(&self) -> PciConfigByteEnable

Retrieve the underlying byte enable.

pub fn fill_intercept_buffer(self, buffer: &mut [u8])

Fill the intercept buffer with the enabled byte lanes of the DWORD.

pub fn into_valid_byte_slice(self) -> &'a mut [u8]

Retrieve a mutable slice of the enabled byte lanes of the DWORD.

pub const fn valid_mask(&self) -> u32

Get the mask of valid bytes.

pub fn set(&mut self, value: u32)

Update the value of the DWORD, honoring byte enables.

pub fn set_low_high(&mut self, low: u16, high: u16)

Update the value of the DWORD, honoring byte enables.

pub fn set_bytes(&mut self, byte0: u8, byte1: u8, byte2: u8, byte3: u8)

Update the value of the DWORD, honoring byte enables.

pub const fn extract(&self) -> u32

Keep only enabled byte lanes from this value.

pub const fn extract_low(self) -> u16

Keep only enabled byte lanes from the low WORD this value.

pub const fn extract_high(self) -> u16

Keep only enabled byte lanes from the high WORD this value.

pub fn reborrow(&mut self) -> ByteEnabledDwordRead<'_>

Reborrow the underlying value.

pub fn restrict( &mut self, byte_enable: PciConfigByteEnable, ) -> Option<ByteEnabledDwordRead<'_>>

Restrict the read to only the provided bytes.

pub fn exclude( &mut self, byte_enable: PciConfigByteEnable, ) -> Option<ByteEnabledDwordRead<'_>>

Exclude the provided bytes from the read.
