Struct Npdu 

pub struct Npdu {
    pub expecting_reply: bool,
    pub priority: NetworkPriority,
    pub destination: Option<NpduAddress>,
    pub source: Option<NpduAddress>,
    pub hop_count: u8,
    pub message_type: Option<NetworkMessageType>,
    pub vendor_id: Option<u16>,
    pub payload: Bytes,
}

Decoded Network Protocol Data Unit (Clause 6.2).

A network-layer message is one whose message_type is set; without it the payload is an APDU.

Fields

expecting_reply: bool

Whether the sender expects a reply.

priority: NetworkPriority

Message priority.

destination: Option<NpduAddress>

Remote destination address, if routed.

source: Option<NpduAddress>

Originating source address (populated by routers).

hop_count: u8

Remaining hop count for routed messages (0-255). Only an NPDU with a destination carries one: without it this is 255, and the encoder leaves it out.

message_type: Option<NetworkMessageType>

The network-layer message type, or None for an APDU.

vendor_id: Option<u16>

Vendor ID for a proprietary network message type (NetworkMessageType::is_proprietary).

payload: Bytes

Payload: either APDU bytes or network message data.

Implementations

impl Npdu

pub fn is_network_message(&self) -> bool

Whether it carries a network-layer message rather than an APDU.

pub fn header_from(view: &Npdu<'_>) -> Self

An owned copy of view’s control information, with an empty payload. The payload is the caller’s to attach: the frame the view was read from, advanced by payload_offset, shares the frame’s buffer instead of copying it.

Trait Implementations

impl Clone for Npdu

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Npdu

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

Formats the value using the given formatter.

impl Default for Npdu

fn default() -> Self

Returns the “default value” for a type.

impl Eq for Npdu

impl PartialEq for Npdu

fn eq(&self, other: &Self) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
