Enum VendorErrorKind 

#[non_exhaustive]
pub enum VendorErrorKind {
    ExternalProgramBlocked,
    ServerDataMismatch,
}

Vendor/firmware-specific response codes observed on real devices but absent from the SRC integration spec (§4.10).

These are deliberately segregated from ServerErrorKind’s documented variants: the spec is the stable contract, whereas these depend on a particular firmware. Descriptions come from the device’s own built-in response-code reference.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

ExternalProgramBlocked

408 — The HDM’s own UI is in use (a user is operating the device’s screens), so external-program access is temporarily blocked. Newland N950: “Գործողություն է կատարվում ՀԴՄ-ի էջերում: Արտաքին ծրագրի աշխատանքը բլոկավորված է:”. Transient — retry once the device screen is idle.

ServerDataMismatch

503 — Mismatch in the data received from the (tax-authority) server. Newland N950: “Սերվերից ստացված տվյալների անհամապատասխանություն”. Indicates the device’s view of a record disagrees with the central server; not resolved by a blind retry.

Implementations

impl VendorErrorKind

pub const fn from_code(code: u16) -> Option<Self>

Map a numeric response code to a vendor variant, if it is a known vendor code.

pub const fn code(self) -> u16

The numeric code for this vendor variant.

pub const fn is_retryable(self) -> bool

Whether retrying unchanged might succeed. Only the transient “UI busy” condition qualifies.

Trait Implementations

impl Clone for VendorErrorKind

fn clone(&self) -> VendorErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for VendorErrorKind

impl Debug for VendorErrorKind

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

Formats the value using the given formatter.

impl Eq for VendorErrorKind

impl PartialEq for VendorErrorKind

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