Enum ValidationWarning 

pub enum ValidationWarning {
    UnknownKey {
        axis: TaxonomyAxis,
        key: String,
    },
    MetadataOversize {
        soft_cap_bytes: usize,
        actual_bytes: usize,
    },
    LegacyTag {
        tag: String,
    },
    MetadataReservedKey {

    },
    MetadataReservedPrefix {
        key: String,
        prefix: String,
    },
}

Forward-compat / hygiene observation. Consumers that want strict validation can promote warnings to errors at their layer; the substrate validator always emits warnings, never errors, for these.

Variants

UnknownKey

A known-axis tag whose key isn’t enumerated in the schema. Forward-compat: a future binding may emit a key this binding doesn’t yet know.

Fields

axis: TaxonomyAxis

Axis the unknown key belongs to.

key: String

Key path under the axis.

MetadataOversize

Total metadata size exceeds the soft cap. Consumed by telemetry counters per CAPABILITY_SYSTEM_PLAN.md Locked decision 2.

Fields

soft_cap_bytes: usize

Soft cap (4 KB by default).

actual_bytes: usize

Actual total bytes across all metadata key+value pairs.

LegacyTag

A Tag::Legacy (untyped) tag. Future major versions may deprecate; surfaced here for operator visibility.

Fields

tag: String

The untyped tag value.

MetadataReservedKey

CR-14: a metadata key collides with a substrate-reserved key (intent, colocate-with, …). User-emitted writes through with_metadata should route around these — collision can override scheduler-internal hints.

Fields

key: String

The reserved metadata key the user wrote into.

MetadataReservedPrefix

CR-14: a metadata key matches a substrate-reserved prefix (tool::, …). Same hazard shape as MetadataReservedKey but matched by prefix rather than exact name.

Fields

key: String

The full key (with the reserved prefix).

prefix: String

The reserved prefix that matched.

Trait Implementations

impl Clone for ValidationWarning

fn clone(&self) -> ValidationWarning

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ValidationWarning

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

Formats the value using the given formatter.

impl PartialEq for ValidationWarning

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