Struct RejectMessageToNetwork 

pub struct RejectMessageToNetwork {
    pub reason: RejectMessageReason,
    pub network: u16,
}

What a Reject-Message-To-Network carries after its type (Clause 6.4.4): one reason octet, then the two-octet network the refused message was for.

It is the one reader and writer of that data in the stack: the router core, the hosted network layer and the client all go through it. It checks layout only; whether the enclosing NPDU is a reject is the caller’s question, and so is what the reason means for a route.

use bacnet_npdu::{RejectMessageReason, RejectMessageToNetwork};

let reject = RejectMessageToNetwork::decode(&[4, 0x0B, 0xB8])?;
assert_eq!(reject.reason, RejectMessageReason::MESSAGE_TOO_LONG);
assert_eq!(reject.network, 3000);
assert_eq!(reject.to_bytes(), [4, 0x0B, 0xB8]);

Fields

reason: RejectMessageReason

Why the message was refused. The set is open: an octet the standard doesn’t name is kept as received.

network: u16

The network the refused message was for (its DNET).

Implementations

impl RejectMessageToNetwork

pub const LEN: usize = 3

The data’s length, in octets.

pub const fn decode(payload: &[u8]) -> Result<Self, RejectLengthError>

Read exactly a reason octet and a network number. Any other length is refused, so a router never acts on a cut-short or padded reject.

pub const fn to_bytes(self) -> [u8; 3]

The data, as sent.
