Struct ReasoningContentBlock 

pub struct ReasoningContentBlock {
    pub block_type: String,
    pub id: Option<String>,
    pub reasoning: Option<String>,
    pub index: Option<BlockIndex>,
    pub extras: Option<HashMap<String, Value>>,
}

Reasoning output from a LLM.

Used to represent reasoning/thinking content from AI models that support chain-of-thought reasoning (e.g., DeepSeek, Ollama, XAI, Groq).

Fields

block_type: String

Type of the content block. Always “reasoning”.

id: Option<String>

Content block identifier.

reasoning: Option<String>

Reasoning text. Either the thought summary or the raw reasoning text itself.

index: Option<BlockIndex>

Index of block in aggregate response. Used during streaming.

extras: Option<HashMap<String, Value>>

Provider-specific metadata.

Implementations

impl ReasoningContentBlock

pub fn new(reasoning: impl Into<String>) -> Self

Create a new reasoning content block.

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

Get the reasoning content.

Trait Implementations

impl Clone for ReasoningContentBlock

fn clone(&self) -> ReasoningContentBlock

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ReasoningContentBlock

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

Formats the value using the given formatter.

impl Default for ReasoningContentBlock

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ReasoningContentBlock

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for ReasoningContentBlock

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
