Trait Implementations

impl Add for HumanMessageChunk

type Output = HumanMessageChunk

The resulting type after applying the + operator.

fn add(self, other: HumanMessageChunk) -> HumanMessageChunk

Performs the + operation.

impl Clone for HumanMessageChunk

fn clone(&self) -> HumanMessageChunk

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for HumanMessageChunk

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for HumanMessageChunk

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<HumanMessageChunk> for BaseMessageChunk

fn from(chunk: HumanMessageChunk) -> Self

Converts to this type from the input type.

impl PartialEq for HumanMessageChunk

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
