Implementations

impl Hcrhdescriptora

pub const fn ndp(&self) -> u8

NumberDownstreamPorts These bits specify the number of downstream ports supported by the root hub.

pub const fn set_ndp(&mut self, val: u8)

NumberDownstreamPorts These bits specify the number of downstream ports supported by the root hub.

pub const fn psm(&self) -> bool

PowerSwitchingMode This bit is used to specify how the power switching of the root hub ports is controlled.

pub const fn set_psm(&mut self, val: bool)

PowerSwitchingMode This bit is used to specify how the power switching of the root hub ports is controlled.

pub const fn nps(&self) -> bool

NoPowerSwitching These bits are used to specify whether power switching is supported or port are always powered.

pub const fn set_nps(&mut self, val: bool)

NoPowerSwitching These bits are used to specify whether power switching is supported or port are always powered.

pub const fn dt(&self) -> bool

DeviceType This bit specifies that the root hub is not a compound device.

pub const fn set_dt(&mut self, val: bool)

DeviceType This bit specifies that the root hub is not a compound device.

pub const fn ocpm(&self) -> bool

OverCurrentProtectionMode This bit describes how the overcurrent status for the root hub ports are reported.

pub const fn set_ocpm(&mut self, val: bool)

OverCurrentProtectionMode This bit describes how the overcurrent status for the root hub ports are reported.

pub const fn nocp(&self) -> bool

NoOverCurrentProtection This bit describes how the overcurrent status for the root hub ports are reported.

pub const fn set_nocp(&mut self, val: bool)

NoOverCurrentProtection This bit describes how the overcurrent status for the root hub ports are reported.

pub const fn potpgt(&self) -> u8

PowerOnToPowerGoodTime This byte specifies the duration the HCD has to wait before accessing a powered-on port of the root hub.

pub const fn set_potpgt(&mut self, val: u8)

PowerOnToPowerGoodTime This byte specifies the duration the HCD has to wait before accessing a powered-on port of the root hub.

Trait Implementations

impl Clone for Hcrhdescriptora

fn clone(&self) -> Hcrhdescriptora

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Hcrhdescriptora

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

Formats the value using the given formatter.

impl Default for Hcrhdescriptora

fn default() -> Hcrhdescriptora

Returns the “default value” for a type.

impl PartialEq for Hcrhdescriptora

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