Struct CachePolicy 

pub struct CachePolicy {
    pub max_age_ms: u64,
    pub stale_while_revalidate_ms: u64,
    pub vary_by_user: bool,
}

Controls how long a cached GraphQL response remains valid.

Fields

max_age_ms: u64

Time in milliseconds for which the entry is considered fresh.

stale_while_revalidate_ms: u64

Additional window (ms) during which the stale entry may be served while a background revalidation is in flight.

vary_by_user: bool

When true the cache key is further distinguished by the authenticated user identity so different users never see each other’s responses.

Implementations

impl CachePolicy

pub fn simple(max_age_ms: u64) -> Self

Construct a simple policy without stale-while-revalidate or per-user variation.

pub fn is_stale_usable(&self, age_ms: u64) -> bool

Returns true if the policy allows serving a stale entry that is age_ms old.
