Enum MessageChunk 

pub enum MessageChunk {
    Human(HumanChunk),
    Ai(AiChunk),
    System(SystemChunk),
    Tool(ToolChunk),
}

A partial message emitted while a model streams. Variants mirror the final Message enum so consumers can match on type before the full message has arrived.

Variants

Human(HumanChunk)

Streaming user-message chunk (rare — most providers stream assistant).

Ai(AiChunk)

Streaming assistant-message chunk.

System(SystemChunk)

Streaming system-message chunk (rare).

Tool(ToolChunk)

Streaming tool-result chunk.

Implementations

impl MessageChunk

pub fn content(&self) -> &str

Plain-text fragment carried by this chunk.

pub fn extend(&mut self, other: MessageChunk) -> Result<()>

Concatenate other into self. Returns an error if the chunks describe different message types (mixing Ai + Human, etc.).

Trait Implementations

impl Clone for MessageChunk

fn clone(&self) -> MessageChunk

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MessageChunk

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for MessageChunk

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for MessageChunk

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
