Trait Implementations

impl Clone for BaseMessageChunk

fn clone(&self) -> BaseMessageChunk

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BaseMessageChunk

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for BaseMessageChunk

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<AIMessageChunk> for BaseMessageChunk

fn from(chunk: AIMessageChunk) -> Self

Converts to this type from the input type.

impl From<ChatMessageChunk> for BaseMessageChunk

fn from(chunk: ChatMessageChunk) -> Self

Converts to this type from the input type.

impl From<FunctionMessageChunk> for BaseMessageChunk

fn from(chunk: FunctionMessageChunk) -> Self

Converts to this type from the input type.

impl From<HumanMessageChunk> for BaseMessageChunk

fn from(chunk: HumanMessageChunk) -> Self

Converts to this type from the input type.

impl From<SystemMessageChunk> for BaseMessageChunk

fn from(chunk: SystemMessageChunk) -> Self

Converts to this type from the input type.

impl From<ToolMessageChunk> for BaseMessageChunk

fn from(chunk: ToolMessageChunk) -> Self

Converts to this type from the input type.

impl PartialEq for BaseMessageChunk

fn eq(&self, other: &BaseMessageChunk) -> 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.

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
