The entry points every sector plugin must export.

The Wasm host calls these after deserialising JSON sector data from the passport payload. Implementations must be deterministic and free of I/O.

Required Methods

fn plugin_identity(&self) -> PluginIdentity

The fields that distinguish this plugin’s identity (see PluginIdentity).

fn schema_version_range(&self) -> SchemaVersionRange

The sector schema version range this plugin supports.

fn validate_input(&self, input: &PluginInput) -> Result<(), PluginError>

Validate the structure and field constraints of the sector input.

Returns Ok(()) if the input is structurally valid, or a descriptive error if a required field is missing or out of range. Prefer PluginError::ValidationErrors with per-field detail over PluginError::InvalidInput for better error reporting.

fn calculate_metrics( &self, input: &PluginInput, ) -> Result<PluginResult, PluginError>

Compute compliance metrics from the sector input.

May return None for fields that do not apply to this sector.

fn generate_passport(&self, input: PluginInput) -> Result<Value, PluginError>

Generate a passport-ready sector data JSON payload.

Applies any normalisation or enrichment required by the sector schema (e.g. rounding, unit conversion). The output is stored verbatim in the DPP. Takes input by value — a pass-through implementation returns it directly instead of cloning.

Provided Methods

fn meta(&self) -> PluginMeta

Returns static metadata about this plugin.

Built from Self::plugin_identity plus the fixed Odal Node license/author/homepage convention. Override directly if a plugin genuinely needs different values.

fn capabilities(&self) -> PluginCapabilities

Returns the plugin’s capability declaration for version negotiation.

Built from Self::schema_version_range plus the standard Validate/ComputeMetrics/GeneratePassport capability set every plugin declares today. Override directly if a plugin needs a different capability set or negotiation limits.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
