pub struct RestRateLimiter { /* private fields */ }

Implementations

impl RestRateLimiter

pub fn new() -> Self

pub fn new_with_budget(max_weight: u32) -> Self

pub async fn acquire(&self, weight: u32) -> Result<(), RateLimitError>

Returns Err(RateLimitError) immediately if the weight budget is exhausted.

pub async fn acquire_blocking(&self, weight: u32, call: &str)

Retries on Err, logging each wait. Resolves once the request is accepted.

pub async fn budget_snapshot(&self) -> (u32, u32, usize)

T4 (2026-09-30): current snapshot of the sliding window — (remaining_weight, max_weight, used_entries). Lets the host application export the info-budget water level as a telemetry gauge (exhaustion becomes a queryable trend, not a surprise).
