Enum ObservationType 

pub enum ObservationType {
    Span,
    Generation,
    ToolCall,
    Retrieval,
}

Type of observation within a trace.

Maps to Langfuse’s observation types. Each type captures different aspects of agent execution.

Variants

Span

Generic span covering any timed operation.

Generation

LLM generation call with prompt/completion data.

ToolCall

Tool invocation with input/output.

Retrieval

RAG retrieval step with query and documents.

Implementations

impl ObservationType

pub const fn as_str(&self) -> &'static str

Returns the string representation for storage and API use.

Trait Implementations

impl Clone for ObservationType

fn clone(&self) -> ObservationType

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ObservationType

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for ObservationType

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for ObservationType

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

Formats the value using the given formatter.

impl PartialEq for ObservationType

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for ObservationType
