Struct BackendCapabilities 

pub struct BackendCapabilities {
    pub backend_id: String,
    pub supported_features: HashSet<ProviderFeature>,
    pub model_families: HashMap<String, ModelFamilyCapabilities>,
}

Capabilities of a specific backend provider.

Two-level model: backend-level defaults plus per-model-family overrides. Feature lookup checks model-family first, falls back to backend-level.

Fields

backend_id: String

Backend identifier (e.g., “anthropic”, “openai”, “passthrough”).

supported_features: HashSet<ProviderFeature>

Backend-level supported features (default for all models).

model_families: HashMap<String, ModelFamilyCapabilities>

Per-model-family capability overrides.

Implementations

impl BackendCapabilities

pub fn none(backend_id: &str) -> Self

Create capabilities with no features (used by passthrough plugin).

pub fn supports(&self, feature: ProviderFeature) -> bool

Check if the backend supports a feature at the backend level.

pub fn model_supports( &self, model_family: &str, feature: ProviderFeature, ) -> bool

Check if a specific model family supports a feature.

Falls back to backend-level if the model family is not registered.

pub fn add_model_family(&mut self, caps: ModelFamilyCapabilities)

Add a model family capability override.

Trait Implementations

impl Clone for BackendCapabilities

fn clone(&self) -> BackendCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BackendCapabilities

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BackendCapabilities

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for BackendCapabilities

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
