Struct AiChunk 

pub struct AiChunk {
    pub content: String,
    pub tool_calls: Vec<ToolCallChunk>,
    pub extras: Map<String, Value>,
}

Streaming fragment for an Ai message. May carry partial text and/or partial tool calls. Concatenating chunks merges text and tool calls (matched by index).

extras is a forward-compatibility bag for provider-specific metadata (finish reasons, logprobs, raw fragments) that should survive round-trips without forcing the core enum to change.

Fields

content: String

Incremental text fragment.

tool_calls: Vec<ToolCallChunk>

Incremental tool-call updates (provider-indexed; same index in two chunks refers to the same call and the second chunk’s fields extend the first).

extras: Map<String, Value>

Provider-specific extras (e.g. finish_reason, logprobs). Merged on extend() — later writes win on key collision.

Trait Implementations

impl Clone for AiChunk

fn clone(&self) -> AiChunk

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AiChunk

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

Formats the value using the given formatter.

impl Default for AiChunk

fn default() -> AiChunk

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AiChunk

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AiChunk

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
