Struct ModelMetadata 

pub struct ModelMetadata {
    pub id: String,
    pub provider: String,
    pub context_limit: Option<u32>,
    pub output_limit: Option<u32>,
    pub pricing: Option<ModelPricing>,
    pub capabilities: ModelCapabilities,
    pub release_date: Option<String>,
    pub source: ModelSource,
    pub variants: Vec<VariantDef>,
}

Static metadata for a known model.

Represents model knowledge (context limits, pricing, capabilities) independent of runtime configuration. Used to inform the agent about model properties without hardcoded fallbacks.

Fields

id: String

Unique model identifier (e.g., “claude-sonnet-4-5-20250929”).

provider: String

Provider name (e.g., “anthropic”, “openai”, “google”).

context_limit: Option<u32>

Maximum context window in tokens.

output_limit: Option<u32>

Maximum output tokens.

pricing: Option<ModelPricing>

Pricing information (per 1M tokens, USD).

capabilities: ModelCapabilities

Model capability flags.

release_date: Option<String>

Model release date (ISO 8601 or similar).

source: ModelSource

Where this metadata originated.

variants: Vec<VariantDef>

Named invocation presets for this model (ADR-048).

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

Formats the value using the given formatter.

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

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for ModelMetadata

fn schema_name() -> Cow<'static, str>

The name of the generated JSON Schema.

fn schema_id() -> Cow<'static, str>

Returns a string that uniquely identifies the schema produced by this type.

fn json_schema(generator: &mut SchemaGenerator) -> Schema

Generates a JSON Schema for this type.

fn inline_schema() -> bool

Whether JSON Schemas generated for this type should be included directly in parent schemas, rather than being re-used where possible using the $ref keyword.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
