Crate synaptic_macros 

Procedural macros for the Synaptic framework.

This crate provides attribute macros that reduce boilerplate when defining tools, runnable chains, graph entrypoints, tasks, middleware hooks, and traced functions.

Macros

Macro	Description
#[tool]	Convert an async fn into a Tool implementor
#[chain]	Convert an async fn into a BoxRunnable
#[entrypoint]	Define a LangGraph-style workflow entry point
#[task]	Define a trackable task inside an entrypoint
#[before_agent]	Middleware: before agent loop
#[before_model]	Middleware: before model call
#[after_model]	Middleware: after model call
#[after_agent]	Middleware: after agent loop
#[wrap_model_call]	Middleware: wrap model call
#[wrap_tool_call]	Middleware: wrap tool call
#[dynamic_prompt]	Middleware: dynamic system prompt
#[traceable]	Add tracing instrumentation

Attribute Macros

after_agent

Middleware: run a hook after the agent loop finishes.

after_model

Middleware: run a hook after each model call.

before_agent

Middleware: run a hook before the agent loop starts.

before_model

Middleware: run a hook before each model call.

chain

Convert an async function into a BoxRunnable<InputType, OutputType> factory.

dynamic_prompt

Middleware: dynamically generate a system prompt based on current messages.

entrypoint

Define a LangGraph-style workflow entry point.

task

Define a trackable task inside an entrypoint.

tool

Convert an async function into a struct that implements synaptic_core::Tool.

traceable

Add tracing instrumentation to an async or sync function.

wrap_model_call

Middleware: wrap the model call with custom logic.

wrap_tool_call

Middleware: wrap a tool call with custom logic.
