Struct DistributedLimiter 

pub struct DistributedLimiter { /* private fields */ }

Shared-store rate limiter: the distributed counterpart of the three governor limiters. Holds the GCRA params for the global per-IP limit, the per-route overrides, and the per-key limit, plus the backing [Store] and the fail-open policy.

Implementations

impl DistributedLimiter

pub fn build(rl: &RateLimitCfg, mode: StoreMode) -> Result<DistributedLimiter>

Build from config for a distributed StoreMode (memory/redis). Compiles the GCRA params for every limit up front, so a bad rate/burst fails at startup/reload — exactly like the local limiter.

pub async fn check_ip_route(&self, ip: IpAddr, path: &str) -> Admit

Pre-auth check: the per-route override matching path (longest prefix), else the global per-IP limit. Keyed per client IP, like the local limiter.

pub async fn check_key(&self, principal: &str) -> Admit

Post-auth check: the per-principal limit (keyed by API-key id / JWT subject). Returns Admit::Allowed when per-key limiting is disabled.
