Struct ModelPreferences 

pub struct ModelPreferences {
    pub hints: Option<Vec<ModelHint>>,
    pub cost_priority: Option<f32>,
    pub speed_priority: Option<f32>,
    pub intelligence_priority: Option<f32>,
}

Preferences for model selection and behavior in sampling requests.

This allows servers to express their preferences for which model to use and how to balance different priorities when the client has multiple model options available.

Fields

hints: Option<Vec<ModelHint>>

Specific model names or families to prefer (e.g., “claude”, “gpt”)

cost_priority: Option<f32>

Priority for cost optimization (0.0 to 1.0, higher = prefer cheaper models)

speed_priority: Option<f32>

Priority for speed/latency (0.0 to 1.0, higher = prefer faster models)

intelligence_priority: Option<f32>

Priority for intelligence/capability (0.0 to 1.0, higher = prefer more capable models)

Trait Implementations

impl Clone for ModelPreferences

fn clone(&self) -> ModelPreferences

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModelPreferences

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ModelPreferences

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl JsonSchema for ModelPreferences

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.

impl PartialEq for ModelPreferences

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
