Enum ThinkingConfig 

pub enum ThinkingConfig {
    Adaptive {
        effort: EffortLevel,
    },
    Enabled {
        budget_tokens: u32,
    },
}

Extended thinking configuration.

Extended thinking lets Claude think step-by-step before responding. Two modes are available:

• Adaptive: Claude decides when and how much to think. Controlled via effort level. Supported on Claude Opus 4.6 and Sonnet 4.6.
• Enabled: Manual extended thinking with an explicit token budget. For older models (Sonnet 4.5, etc.) or when a specific budget is needed.

Trait Implementations

impl Clone for ThinkingConfig

fn clone(&self) -> ThinkingConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThinkingConfig

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ThinkingConfig

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ThinkingConfig

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
