Module middleware 

Middleware pipelines for agents, chat clients, and function invocation.

Rust equivalent of agent_framework._middleware. Middleware receives an owned context and a Next continuation. Call next.run(ctx) to continue the chain, mutate the context to observe/override results, or return the context directly (optionally with terminate = true) to short-circuit.

Structs

AgentContext

Context flowing through the agent middleware pipeline.

ChatContext

Context flowing through the chat middleware pipeline.

FnMiddleware

Adapter to build a Middleware from an async closure.

FunctionInvocationContext

Context flowing through the function middleware pipeline.

LiveToolList

The live, mutable tool list of an in-flight agent run (progressive tool exposure).

MiddlewarePipeline

A pipeline of middleware of a single category.

Next

The continuation passed to a Middleware. Calling Next::run invokes the remaining middleware and, finally, the terminal handler.

Traits

Middleware

A middleware that transforms a context of type C.

Type Aliases

AgentMiddleware

Convenience type aliases for each middleware category.

ChatMiddleware

Chat middleware operates on a ChatContext.

FunctionMiddleware

Function middleware operates on a FunctionInvocationContext.

Terminal

The terminal handler invoked at the end of a middleware chain.
