Struct HostEnv 

pub struct HostEnv {
    pub id_generator: Arc<dyn IdGenerator>,
    pub clock: Arc<dyn Clock>,
}

Bundle of host-environment capabilities. Used as the single Option<Arc<HostEnv>> slot on AgentConfig and SessionOptions — avoids growing two parallel Arc<dyn …> fields.

Fields

id_generator: Arc<dyn IdGenerator>

clock: Arc<dyn Clock>

Implementations

impl HostEnv

pub fn new(id_generator: Arc<dyn IdGenerator>, clock: Arc<dyn Clock>) -> Self

Construct a host env from concrete components.

pub fn system() -> Self

Default system-backed host env: random UUIDs + wall clock. Equivalent to pre-P2 behaviour.

pub fn next_id(&self) -> String

Shortcut for self.id_generator.next_id().

pub fn now_ms(&self) -> u64

Shortcut for self.clock.now_ms().
