Modules

approval

Approval types for human-in-the-loop (HITL) gates.

capability

Model capability registry.

checkpoint

persistence

prelude

registry

runnable

serde

state

token_budget

Token budget cap for LLM context windows.

Structs

CallbackManager

CancellationToken

A token which can be used to signal a cancellation request to one or more tasks.

Chain

Document

JsonOutputParser

A parser that parses a JSON string (or LlmResponse content) into a structured type or Value.

LlmInput

LLM call parameters captured at start time.

LlmRequest

LlmResponse

LlmResult

LLM call results captured at end time.

Message

OutputFixingParser

A parser/chain that wraps an LLM and a base parser. It attempts to invoke the LLM and parse the result. If parsing fails, it feeds the error back to the LLM to generate a fix.

RateLimited

Retrying

RunConfig

RunContext

RunnableBinding

A Runnable that has arguments bound to it.

RunnableParallel

RunnableWithFallbacks

RuntimeChain

A runtime-constructed chain that operates on Value. This is used for deserialization where types are not known at compile time.

SearchResult

StrOutputParser

A parser that converts LlmResponse or String into a String. If input is LlmResponse, it extracts the content.

StructuredOutputParser

A parser that extracts structured output from LlmResponse. It prioritizes tool_calls (first call args), then falls back to parsing content as JSON.

TimeLimited

TokenUsage

Token consumption for cost tracking and optimization.

ToolCall

Traits

BaseOutputParser

Trait for output parsers that can transform input into a specific output. This is a specialized version of Runnable for parsing logic.

Bindable

A trait for input types that can have arguments bound to them.

CallbackHandler

Embedding

HasFinalOutput

HasMetadataFilter

HasQuery

HasRetrievedDocs

HasUserInput

IntoValue

Converts a value into Value, falling back to Value::Null on serialization errors (v0 behavior).
