Struct ReasoningConfig 

pub struct ReasoningConfig {
    pub enabled: Option<bool>,
    pub effort: Option<ReasoningEffort>,
    pub summary: Option<ReasoningSummary>,
}

Reasoning-model controls for a chat completion request.

Three independent knobs, each serialized only when set:

• effort maps to the official OpenAI Chat Completions reasoning_effort parameter (accepted by OpenAI and most OpenAI-compatible gateways, including OpenRouter).
• enabled maps to the OpenRouter extension object reasoning: {"enabled": bool}. enabled: false stops reasoning models from emitting chain-of-thought into content (which would otherwise also burn max_tokens on reasoning). This key is only sent when you explicitly set it — pure-OpenAI endpoints never see it otherwise.
• summary rides inside the same reasoning object; the key and its values (auto/concise/detailed) follow the official OpenAI Responses-API reasoning.summary parameter, which OpenRouter’s chat completions endpoint also accepts.

Forwarded by OpenAIClient in both complete and stream_complete. AnthropicClient forwards effort as output_config.effort (how Claude 5.5-class models set thinking depth; the legacy thinking.budget_tokens form is rejected there) and ignores enabled/summary.

Fields

enabled: Option<bool>

On/off toggle for providers with an explicit switch (OpenRouter reasoning.enabled).

effort: Option<ReasoningEffort>

How much the model reasons (OpenAI reasoning_effort).

summary: Option<ReasoningSummary>

Reasoning summary style (OpenAI Responses reasoning.summary).

Implementations

impl ReasoningConfig

pub fn disabled() -> Self

Turn reasoning off where the provider supports an explicit switch (serializes reasoning: {"enabled": false} — the OpenRouter form).

pub fn effort(effort: ReasoningEffort) -> Self

Request a specific reasoning effort (serializes reasoning_effort).

Trait Implementations

impl Clone for ReasoningConfig

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReasoningConfig

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

Formats the value using the given formatter.

impl Default for ReasoningConfig

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ReasoningConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for ReasoningConfig

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
