Enum ThinkingConfig 

pub enum ThinkingConfig {
    Enabled {
        budget_tokens: u32,
        display: Option<ThinkingDisplay>,
    },
    Adaptive {
        display: Option<ThinkingDisplay>,
    },
    Disabled,
}

Available on crate feature anthropic-client only.

Unified thinking configuration covering all modes.

Uses #[serde(tag = "type")] for internally-tagged serialisation.

Variants

• Enabled — Budget-based thinking (legacy, deprecated on 4.6 models).
• Adaptive — Adaptive thinking for Opus 4.6 / Sonnet 4.6. Pair with output_config.effort to control reasoning depth.
• Disabled — Thinking disabled.

Variants

Enabled

Budget-based thinking (deprecated on 4.6 models).

Fields

budget_tokens: u32

Token budget for thinking. Must be ≥1024 and less than max_tokens.

display: Option<ThinkingDisplay>

Optional display control.

Adaptive

Adaptive thinking for Opus 4.6 / Sonnet 4.6. Use output_config.effort to control reasoning depth.

Fields

display: Option<ThinkingDisplay>

Optional display control.

Disabled

Thinking disabled.

Implementations

impl ThinkingConfig

pub fn num_tokens(&self) -> u32

Returns the number of budget tokens configured for thinking. Returns 0 if thinking is disabled or adaptive.

pub fn enabled(budget_tokens: u32) -> ThinkingConfig

Create a budget-based thinking configuration (legacy).

pub fn adaptive() -> ThinkingConfig

Create an adaptive thinking configuration. Pair with output_config.effort to control reasoning depth.

pub fn disabled() -> ThinkingConfig

Create a disabled thinking configuration.

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<(), Error>

Formats the value using the given formatter.

impl Default for ThinkingConfig

fn default() -> ThinkingConfig

Returns the “default value” for a type.

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

fn deserialize<__D>( __deserializer: __D, ) -> Result<ThinkingConfig, <__D as Deserializer<'de>>::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 as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ThinkingConfig

impl StructuralPartialEq for ThinkingConfig
