pub struct StatusRegister(/* private fields */);

Implementations

impl StatusRegister

pub fn new(value: u16) -> Self

pub fn parity_error_detected(&self) -> bool

Will be true whenever the device detects a parity error, even if parity error handling is disabled.

pub fn signalled_system_error(&self) -> bool

Will be true whenever the device asserts SERR#.

pub fn received_master_abort(&self) -> bool

Will return true, by a master device, whenever its transaction (except for Special Cycle transactions) is terminated with Master-Abort.

pub fn received_target_abort(&self) -> bool

Will return true, by a master device, whenever its transaction is terminated with Target-Abort.

pub fn signalled_target_abort(&self) -> bool

Will return true whenever a target device terminates a transaction with Target-Abort.

pub fn devsel_timing(&self) -> Result<DevselTiming, ()>

The slowest time that a device will assert DEVSEL# for any bus command except Configuration Space read and writes.

For PCIe always set to Fast

pub fn master_data_parity_error(&self) -> bool

This returns true only when the following conditions are met:

• The bus agent asserted PERR# on a read or observed an assertion of PERR# on a write
• the agent setting the bit acted as the bus master for the operation in which the error occurred
• bit 6 of the Command register (Parity Error Response bit) is set to 1.

pub fn fast_back_to_back_capable(&self) -> bool

If returns true the device can accept fast back-to-back transactions that are not from the same agent; otherwise, transactions can only be accepted from the same agent.

For PCIe always set to false

pub fn capable_66mhz(&self) -> bool

If returns true the device is capable of running at 66 MHz; otherwise, the device runs at 33 MHz.

For PCIe always set to false

pub fn has_capability_list(&self) -> bool

If returns true the device implements the pointer for a New Capabilities Linked list; otherwise, the linked list is not available.

For PCIe always set to true

pub fn interrupt_status(&self) -> bool

Represents the state of the device’s INTx# signal. If returns true and bit 10 of the Command register (Interrupt Disable bit) is set to 0 the signal will be asserted; otherwise, the signal will be ignored.

Trait Implementations

impl Clone for StatusRegister

fn clone(&self) -> StatusRegister

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StatusRegister

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

Formats the value using the given formatter.

impl PartialEq for StatusRegister

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

This method tests for self and other values to be equal, and is used by ==.

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

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