Implementations

impl<'r> Request<'r>

pub fn pdu_len(&self) -> usize

Number of bytes required for a serialized PDU frame.

Trait Implementations

impl<'r> Clone for Request<'r>

fn clone(&self) -> Request<'r>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'r> Debug for Request<'r>

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

Formats the value using the given formatter.

impl<'r> Encode for Request<'r>

fn encode(&self, buf: &mut [u8]) -> Result<usize, Error>

impl<'r> From<Request<'r>> for FunctionCode

fn from(r: Request<'r>) -> Self

Converts to this type from the input type.

impl<'r> PartialEq for Request<'r>

fn eq(&self, other: &Request<'r>) -> 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<'r> TryFrom<&'r [u8]> for Request<'r>

type Error = Error

The type returned in the event of a conversion error.

fn try_from(bytes: &'r [u8]) -> Result<Self, Error>

Performs the conversion.

impl<'r> Copy for Request<'r>

impl<'r> Eq for Request<'r>

impl<'r> StructuralPartialEq for Request<'r>
