Implementations

impl ContextStore

pub fn new(base: HashMap<String, String>) -> Self

base is the merged static ⊕ env map (env precedence applied by the caller).

pub fn push(&self, values: HashMap<String, String>, ttl: Option<Duration>)

Replace the overlay with values, expiring after ttl (None = no expiry).

pub fn clear(&self)

Drop the overlay, reverting to base.

pub fn resolve(&self) -> ResolvedContext

pub fn resolve_at(&self, now: Instant) -> ResolvedContext

Base overlaid by a live overlay (overlay keys win). Expired overlay is dropped.
