Struct ThinkingPart 

pub struct ThinkingPart {
    pub content: String,
    pub id: Option<String>,
    pub signature: Option<String>,
    pub provider_name: Option<String>,
    pub provider_details: Option<Map<String, Value>>,
}

Thinking/reasoning content part.

Used for models that support “thinking” or chain-of-thought reasoning, like Claude’s extended thinking feature.

Fields

content: String

The thinking content.

id: Option<String>

Optional unique identifier for this part.

signature: Option<String>

Optional signature for verification.

provider_name: Option<String>

Provider name that generated this thinking content.

provider_details: Option<Map<String, Value>>

Provider-specific details/metadata.

Implementations

impl ThinkingPart

pub const PART_KIND: &'static str = "thinking"

Part kind identifier.

pub const REDACTED_THINKING_ID: &'static str = "redacted_thinking"

ID used for Anthropic redacted thinking blocks.

pub const REDACTED_CONTENT_ID: &'static str = "redacted_content"

ID used for Bedrock redacted content blocks.

pub fn new(content: impl Into<String>) -> ThinkingPart

Create a new thinking part.

pub fn redacted( signature: impl Into<String>, provider_name: impl Into<String>, ) -> ThinkingPart

Create a redacted thinking part.

Redacted thinking blocks contain encrypted/hidden content. The signature must be preserved and sent back to the API in subsequent requests.

Arguments

• signature - The encrypted/encoded data from the provider
• provider_name - The provider that generated this (e.g., “anthropic”, “bedrock”)

pub fn redacted_with_id( id: impl Into<String>, signature: impl Into<String>, provider_name: impl Into<String>, ) -> ThinkingPart

Create a redacted thinking part with a specific ID.

pub fn part_kind(&self) -> &'static str

Get the part kind.

pub fn with_id(self, id: impl Into<String>) -> ThinkingPart

Set the part ID.

pub fn with_signature(self, signature: impl Into<String>) -> ThinkingPart

Set the signature.

pub fn with_provider_name(self, name: impl Into<String>) -> ThinkingPart

Set the provider name.

pub fn with_provider_details(self, details: Map<String, Value>) -> ThinkingPart

Set provider-specific details.

pub fn is_empty(&self) -> bool

Check if the content is empty.

pub fn is_redacted(&self) -> bool

Check if this is a redacted thinking block.

Redacted blocks have their content hidden/encrypted by the provider. The signature field contains the encrypted data that must be round-tripped back to the API.

pub fn redacted_signature(&self) -> Option<&str>

Get the signature if this is a redacted block.

Trait Implementations

impl Clone for ThinkingPart

fn clone(&self) -> ThinkingPart

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ThinkingPart

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

Formats the value using the given formatter.

impl Default for ThinkingPart

fn default() -> ThinkingPart

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ThinkingPart

fn deserialize<__D>( __deserializer: __D, ) -> Result<ThinkingPart, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<ThinkingPart> for ModelResponsePart

fn from(p: ThinkingPart) -> ModelResponsePart

Converts to this type from the input type.

impl PartialEq for ThinkingPart

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

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.
