Enum DataPhase 

pub enum DataPhase<'a> {
    In(&'a mut [u8]),
    Out(&'a [u8]),
    None,
}

The data phase of a USB control-endpoint transaction

A transaction on a control endpoint involves one of:

• IN (data transferred from device to host)
• OUT (data transferred from host to device)
• neither (the Setup packet contains all the relevant data)

See USB 2.0 section 8.5.3 and fiture 8-37.

Variants

In(&'a mut [u8])

IN transaction (device-to-host)

Out(&'a [u8])

OUT transaction (host-to-device)

None

No data phase in control transaction

Implementations

impl DataPhase<'_>

pub fn is_in(&self) -> bool

Is this DataPhase an IN variant?

pub fn is_out(&self) -> bool

Is this DataPhase an OUT variant?

pub fn is_none(&self) -> bool

Is this DataPhase a no-data variant?

pub fn in_with<F: FnOnce(&mut [u8])>(&mut self, f: F)

If this DataPhase is an IN variant, call the supplied function on the received data

Trait Implementations

impl<'a> Debug for DataPhase<'a>

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

Formats the value using the given formatter.

impl<'a> PartialEq for DataPhase<'a>

fn eq(&self, other: &DataPhase<'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.
