Struct ModelMetadata 

pub struct ModelMetadata {
    pub model_id: String,
    pub safety_tier: Option<ModelSafetyTier>,
    pub provider: Option<String>,
    pub provenance_class: GovernedProvenanceEvidenceClass,
}

Metadata describing the model executing a tool-bearing agent.

Carried on ToolCallRequest so the kernel can evaluate Constraint::ModelConstraint against the calling model’s identity and safety tier.

Fields

model_id: String

Model identifier (e.g. "claude-opus-4", "gpt-5").

safety_tier: Option<ModelSafetyTier>

Declared safety tier, when available.

provider: Option<String>

Optional provider label (e.g. "anthropic", "openai").

provenance_class: GovernedProvenanceEvidenceClass

Provenance class describing how Chio learned this model identity.

Defaults to asserted for backward compatibility with legacy callers that only forwarded raw model identifiers.

Implementations

impl ModelMetadata

pub fn with_provenance_class( self, provenance_class: GovernedProvenanceEvidenceClass, ) -> ModelMetadata

Trait Implementations

impl Clone for ModelMetadata

fn clone(&self) -> ModelMetadata

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModelMetadata

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ModelMetadata

fn deserialize<__D>( __deserializer: __D, ) -> Result<ModelMetadata, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<&ModelMetadata> for ModelMetadataReceiptMetadata

fn from(value: &ModelMetadata) -> ModelMetadataReceiptMetadata

Converts to this type from the input type.

impl PartialEq for ModelMetadata

fn eq(&self, other: &ModelMetadata) -> 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 ModelMetadata

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ModelMetadata
