Implementations

impl StandardRequest

pub fn parse( bmrequesttype: u8, brequest: u8, wvalue: u16, windex: u16, wlength: u16, ) -> Result<Self, ()>

Parses a standard request

Trait Implementations

impl Clone for StandardRequest

fn clone(&self) -> StandardRequest

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for StandardRequest

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

Formats the value using the given formatter.

impl PartialEq for StandardRequest

fn eq(&self, other: &StandardRequest) -> 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 Copy for StandardRequest

impl StructuralPartialEq for StandardRequest
