Trait CoreState 

pub trait CoreState: State {
    // Required methods
    fn messages(&self) -> &[Message];
    fn messages_mut(&mut self) -> &mut Vec<Message>;
    fn iterations(&self) -> u32;
    fn set_iterations(&mut self, n: u32);
    fn thread_id(&self) -> &str;
    fn context(&self) -> &ExecutionContext;
    fn context_mut(&mut self) -> &mut ExecutionContext;

    // Provided method
    fn runtime_result_metadata(&self) -> HashMap<String, Value> { ... }
}

Core fields every agent state MUST have. Generated by #[derive(CoreState)] or detected via #core fields in #[derive(State)].

Generic nodes that work on ANY agent state bound on this trait:

#[node]
async fn prepare<S: CoreState>(state: &S) -> NodeResult<S::Update> { ... }

Required Methods

fn messages(&self) -> &[Message]

fn messages_mut(&mut self) -> &mut Vec<Message>

fn iterations(&self) -> u32

fn set_iterations(&mut self, n: u32)

fn thread_id(&self) -> &str

fn context(&self) -> &ExecutionContext

fn context_mut(&mut self) -> &mut ExecutionContext

Provided Methods

fn runtime_result_metadata(&self) -> HashMap<String, Value>

Optional structured metadata projection surfaced on runtime results.

Most states do not need this and can use the default empty projection. Specialized runtime-owned states can override it to expose structured execution details at the ExecutionResult boundary.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
