Attribute Macro entrypoint 

#[entrypoint]

Define a LangGraph-style workflow entry point.

Converts an async function that takes serde_json::Value and returns Result<serde_json::Value, SynapticError> into a factory function that returns an Entrypoint.

Attributes

• name = "..." — override the entrypoint name (defaults to the function name)
• checkpointer = "..." — hint which checkpointer backend to use (e.g. "memory")

Example

use synaptic_macros::entrypoint;
use synaptic_core::SynapticError;
use serde_json::Value;

#[entrypoint(checkpointer = "memory")]
async fn my_workflow(input: Value) -> Result<Value, SynapticError> {
    Ok(input)
}

// `my_workflow` is now a function returning `Entrypoint`
let ep = my_workflow();
