Enum Passcode 

pub enum Passcode {
    Verified(u16),
    ReceiveOnly,
}

APRS-IS authentication passcode.

Per the APRS-IS authentication spec, a valid passcode is a 15-bit positive integer computed from the callsign via the public aprs_is_passcode hash. Clients that don’t hold a verified passcode (e.g. read-only monitors) may authenticate as “receive-only” which maps to the wire value -1.

This enum replaces the previous i32 field that used -1 as a magic sentinel, making illegal states unrepresentable.

Variants

Verified(u16)

A verified 15-bit passcode computed from the station callsign.

ReceiveOnly

Receive-only connection — the server will accept incoming packets from us but will not forward any packets we transmit to RF.

Implementations

impl Passcode

pub fn for_callsign(callsign: &str) -> Self

Compute the passcode for a callsign using the public APRS-IS hash algorithm.

pub const fn as_wire(self) -> i32

Convert to the wire representation used in the APRS-IS login string. Verified(n) → n, ReceiveOnly → -1.

Trait Implementations

impl Clone for Passcode

fn clone(&self) -> Passcode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Passcode

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

Formats the value using the given formatter.

impl Display for Passcode

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

Formats the value using the given formatter.

impl Hash for Passcode

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Passcode

fn eq(&self, other: &Passcode) -> 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.
