Enum DIR

pub enum DIR {
    To = 0,
    From = 1,
}

Direction of transaction This bit is written by the hardware according to the direction of the successful transaction, which generated the interrupt request. If DIR bit = 0, VTTX bit is set in the USB_CHEPnR register related to the interrupting endpoint. The interrupting transaction is of IN type (data transmitted by the USB peripheral to the host PC). If DIR bit = 1, VTRX bit or both VTTX/VTRX are set in the USB_CHEPnR register related to the interrupting endpoint. The interrupting transaction is of OUT type (data received by the USB peripheral from the host PC) or two pending transactions are waiting to be processed. This information can be used by the application software to access the USB_CHEPnR bits related to the triggering transaction since it represents the direction having the interrupt pending. This bit is read-only.

Value on reset: 0

Variants

To = 0

0: Data transmitted by the USB peripheral to the host PC

From = 1

1: Data received by the USB peripheral from the host PC

Trait Implementations

impl Clone for DIR

fn clone(&self) -> DIR

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DIR

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

Formats the value using the given formatter.

impl Format for DIR

fn format(&self, f: Formatter<'_>)

Writes the defmt representation of self to fmt.

impl From<DIR> for bool

fn from(variant: DIR) -> Self

Converts to this type from the input type.

impl PartialEq for DIR

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