Struct RequestType 

pub struct RequestType {
    pub direction: Direction,
    pub control_type: ControlType,
    pub recipient: Recipient,
}

USB control request type (bmRequestType).

Encodes the three sub-fields of bmRequestType (USB 2.0 spec Table 9-2): direction (bit 7), type (bits 6..5) and recipient (bits 4..0).

Fields

direction: Direction

Transfer direction (IN = device→host, OUT = host→device).

control_type: ControlType

Whether this is a standard, class, vendor, or reserved request.

recipient: Recipient

Recipient of the request.

Implementations

impl RequestType

pub const fn to_bits(self) -> u8

Encode this request type to its wire-format bmRequestType byte.

pub const fn from_bits(b: u8) -> Self

Decode a wire-format bmRequestType byte.

Reserved type values decode to ControlType::Reserved; reserved recipient values (4..=31) decode to Recipient::Reserved.

Trait Implementations

impl Clone for RequestType

fn clone(&self) -> RequestType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RequestType

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

Formats the value using the given formatter.

impl Format for RequestType

where Direction: Format, ControlType: Format, Recipient: Format,

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

Writes the defmt representation of self to fmt.

impl PartialEq for RequestType

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