Struct FunctionQuota 

pub struct FunctionQuota {
    pub max_invocations: Option<u64>,
    pub window_secs: Option<u64>,
    pub max_concurrent: Option<u32>,
}

Per-function usage quota (FA-4) — require-style knobs enforced host-side, fail-closed (over the limit ⇒ 429). Accounting, not billing: this bounds abuse, it does not charge. All limits are per node today (a cluster-wide token bucket is future work); None on a field means that dimension is unlimited.

Fields

max_invocations: Option<u64>

Max invocations admitted within window_secs (a fixed window: the counter resets when the window rolls over).

window_secs: Option<u64>

The rate-limit window length in seconds (defaults to 60 when a max_invocations cap is set).

max_concurrent: Option<u32>

Max concurrent in-flight invocations for this function (per node).

Implementations

impl FunctionQuota

pub fn is_unset(&self) -> bool

Whether any dimension is set (an all-None quota is a no-op the caller can skip entirely).

pub fn window(&self) -> u64

The effective rate-limit window (defaults to 60s).
