Enum IssueSource 

pub enum IssueSource {
    XsdLayer,
    ProseRule,
    EngineInternal,
}

Which authority produced a validation finding.

Encodes the “prose vs XSD” provenance distinction that SMPTE ST 2067-3 §5.1 calls out (“the prose document takes precedence on conflict”), so callers can filter, group, or apply per-source severity overrides without inspecting the code string.

Currently inferred from the code prefix on a ValidationIssue (see ValidationIssue::source) — no engine code needs to set it explicitly. If inference ever becomes ambiguous (e.g. a non-XSD engine internal rule that wants the XSD/ prefix for catalogue reasons), we can add a with_source() builder without changing the public shape.

Variants

XsdLayer

Came from the runtime XSD validator (uppsala). Schema-layer: the structural subset of the spec that the XSD DSL can express.

ProseRule

Came from a hand-rolled prose-cited rule. Semantic/cross-field/ value-set checks that XSD can’t express; the rule’s code typically cites a SMPTE prose section (e.g. ST2067-2:2020:6.4.2).

EngineInternal

Came from imferno engine internals — parse failures, package structure checks, manifest issues — not directly traceable to a single SMPTE spec section.

Implementations

impl IssueSource

pub fn from_code(code: &str) -> Self

Infer the source authority from a catalogue code string.

Inference rules (checked top-to-bottom):

• XSD/... → XsdLayer
• IMFERNO:... or IMFERNO/... → EngineInternal
• everything else → ProseRule (most catalogue codes cite a spec §)

Trait Implementations

impl Clone for IssueSource

fn clone(&self) -> IssueSource

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for IssueSource

impl Debug for IssueSource

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for IssueSource

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for IssueSource

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

Formats the value using the given formatter.

impl Eq for IssueSource

impl Hash for IssueSource

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 IssueSource

fn eq(&self, other: &IssueSource) -> 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 Serialize for IssueSource

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
