Macro core_state_fields 

macro_rules! core_state_fields {
    () => { ... };
}

Embeds the standard CoreState fields into a state struct.

These fields are required for any state that implements CoreState. The #[core] attribute signals to #[derive(State)] that it should generate the CoreState trait impl.

Usage

use pe_core::core_state_fields;

#[derive(State, Clone, Debug, Serialize, Deserialize)]
struct MyAgentState {
    core_state_fields!(),

    // Your custom fields here
    topic: String,
}

Expands to

#[core]
messages: Vec<Message>,
#[core]
iterations: u32,
#[core]
thread_id: String,
#[core]
context: ExecutionContext,
