Struct ByteEnabledDwordWrite 

pub struct ByteEnabledDwordWrite { /* private fields */ }

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

Implementations

impl ByteEnabledDwordWrite

pub const fn new(value: u32, byte_enable: PciConfigByteEnable) -> Self

Create a byte-enabled DWORD value.

pub const fn with_all_bytes_enabled(value: u32) -> Self

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

pub fn from_intercept_buffer( byte_enable: PciConfigByteEnable, buffer: &[u8], ) -> Self

Create a byte-enabled DWORD value from a slice of bytes.

pub fn as_valid_byte_slice(&self) -> &[u8]

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

pub const fn is_full(self) -> bool

Returns true if all byte lanes are enabled.

pub const fn byte_enable(&self) -> PciConfigByteEnable

Retrieve the underlying byte enable.

pub const fn valid_mask(self) -> u32

Get the mask of valid bytes.

pub const fn merge(self, current_value: u32) -> u32

Merge enabled byte lanes from this value into current_value.

pub const fn merge_into(self, current_value: &mut u32)

Merge enabled byte lanes from this value into current_value (read-modify-write).

pub const fn merge_low(self, current_value: u16) -> u16

Merge enabled byte lanes from the low WORD of this value into current_value.

pub const fn merge_high(self, current_value: u16) -> u16

Merge enabled byte lanes from the high WORD of this value into current_value.

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.

Trait Implementations

impl Clone for ByteEnabledDwordWrite

fn clone(&self) -> ByteEnabledDwordWrite

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ByteEnabledDwordWrite

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

Formats the value using the given formatter.

impl Inspect for ByteEnabledDwordWrite

fn inspect(&self, req: Request<'_>)

Inspects the object.

impl PartialEq for ByteEnabledDwordWrite

fn eq(&self, other: &ByteEnabledDwordWrite) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
