Struct ModelCapabilities 

pub struct ModelCapabilities {
    pub supports_thinking: bool,
    pub supports_vision: bool,
    pub supports_tool_use: bool,
    pub supports_streaming: bool,
    pub supports_structured_output: bool,
    pub max_context_window: Option<u64>,
    pub max_output_tokens: Option<u64>,
}

Per-model capability flags and limits.

Populated from the model catalog or set manually. The agent loop can inspect these before enabling provider-specific features (e.g. skip thinking blocks when supports_thinking is false).

Fields

supports_thinking: bool

Whether the model supports extended-thinking / chain-of-thought blocks.

supports_vision: bool

Whether the model accepts image content blocks.

supports_tool_use: bool

Whether the model can invoke tools.

supports_streaming: bool

Whether the model supports streaming responses.

supports_structured_output: bool

Whether the model supports structured (JSON schema) output.

max_context_window: Option<u64>

Maximum input context window in tokens, if known.

max_output_tokens: Option<u64>

Maximum output tokens per response, if known.

Implementations

pub const fn with_tool_use(self, val: bool) -> Self

pub const fn with_streaming(self, val: bool) -> Self

pub const fn with_structured_output(self, val: bool) -> Self

pub const fn with_max_context_window(self, tokens: u64) -> Self

pub const fn with_max_output_tokens(self, tokens: u64) -> Self

Trait Implementations

impl Clone for ModelCapabilities

fn clone(&self) -> ModelCapabilities

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ModelCapabilities

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

Formats the value using the given formatter.

impl Default for ModelCapabilities

fn default() -> ModelCapabilities

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ModelCapabilities

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ModelCapabilities

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
