Trait Implementations

impl Default for InterfaceDescriptor

fn default() -> Self

Returns the “default value” for a type.

impl Descriptor for InterfaceDescriptor

fn size(&self) -> usize

Serialized size of Descriptor

fn write_to_unchecked(&self, buf: &[Cell<u8>]) -> usize

Same as write_to(), but doesn’t check that buf is long enough before indexing into it. This should be used only if the result of size() is first consulted.

fn write_to(&self, buf: &[Cell<u8>]) -> usize

Serialize the descriptor to a buffer for transmission on the bus
