Struct CacheConfig 

pub struct CacheConfig {
    pub default_ttl: Duration,
    pub max_entries: usize,
    pub cacheable_methods: HashSet<String>,
    pub tier_resolver: Option<CacheTierResolver>,
}

Configuration for the response cache.

Fields

default_ttl: Duration

Default time-to-live for cached entries.

When tier_resolver is None, this TTL is used for all entries in cacheable_methods. When a tier resolver is present, this is used as a fallback only if a tier’s default TTL is somehow None.

max_entries: usize

Maximum number of entries to store.

cacheable_methods: HashSet<String>

Set of RPC method names that are eligible for caching.

When tier_resolver is None, only methods in this set are cached. When tier_resolver is Some, this set is ignored and the resolver decides cacheability (any tier except NeverCache).

tier_resolver: Option<CacheTierResolver>

Optional tier resolver for tiered caching.

When Some, the resolver classifies each request into a CacheTier and applies tier-specific TTLs. When None, the cache uses the flat default_ttl + cacheable_methods behavior.
