Struct CacheConfig 

pub struct CacheConfig {
    pub enabled: bool,
    pub url: String,
    pub prefix: String,
    pub default_ttl_secs: u64,
    pub timeout_secs: u64,
}

An optional Redis cache.

Nothing in the framework caches through it: resources, permissions and the admin manifest all behave exactly the same whether it is configured or not. It exists so a function has somewhere to put a rate-limit counter, a memoised third-party response or a short-lived token — see the cache_* helpers on a function’s Context.

Off unless url is set, so an app that doesn’t want one pays nothing.

Fields

enabled: bool

Turn the configured cache off without deleting its settings.

url: String

Connection URL, e.g. redis://127.0.0.1:6379 or rediss://…/0. Empty (the default) means no cache.

prefix: String

Prepended to every key a function uses, so several apps can share one Redis without colliding.

default_ttl_secs: u64

Expiry applied to a set that doesn’t ask for one. 0 = keys persist.

timeout_secs: u64

How long one cache operation may take before it is abandoned.
