Struct PortKey

struct PortKey {
    port_state: PortState,
    pci_address: PciAddress,
}

PortKey is a unique identifier of ports with an ordering defined on it.

Ports are ordered by whose downstream device would be discovered first by the guest OS. Empty ports without pending events are ordered before those with pending events. When multiple empty ports without pending events are available, they are ordered by PCI enumeration.

Fields

port_state: PortState

pci_address: PciAddress

Trait Implementations

impl Ord for PortKey

fn cmp(&self, other: &PortKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PortKey

fn eq(&self, other: &PortKey) -> 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.

impl PartialOrd for PortKey

fn partial_cmp(&self, other: &PortKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
