}

This specifies the service ratio between Control and Bulk EDs. Before processing any of the nonperiodic lists, HC must compare the ratio specified with its internal count on how many nonempty Control EDs have been processed, in determining whether to continue serving another Control ED or switching to Bulk EDs. The internal count will be retained when crossing the frame boundary. In case of reset, HCD is responsible for restoring this value.

Value on reset: 0

Trait Implementations

impl Clone for CONTROL_BULK_SERVICE_RATIO_A

fn clone(&self) -> CONTROL_BULK_SERVICE_RATIO_A

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for CONTROL_BULK_SERVICE_RATIO_A

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

Formats the value using the given formatter.

impl From<CONTROL_BULK_SERVICE_RATIO_A> for u8

fn from(variant: CONTROL_BULK_SERVICE_RATIO_A) -> Self

Converts to this type from the input type.

impl PartialEq for CONTROL_BULK_SERVICE_RATIO_A

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