Method add

ipld/resolver/src/limiter.rs:32–34

Try to add a certain amount of resources consumed to a key. Return `true` if the key was within limits, `false` if it needs to wait. The [`RateLimit`] is passed in so that we can update it dynamically based on how much data we anticipate we will have to serve.

(&mut self, limit: &RateLimit, key: K, cost: u32)

    /// The [`RateLimit`] is passed in so that we can update it dynamically
    /// based on how much data we anticipate we will have to serve.
    pub fn add(&mut self, limit: &RateLimit, key: K, cost: u32) -> bool {
        self.add_at(limit, key, cost, Instant::now())
    }

    /// Same as [`RateLimiter::add`] but allows passing in the time, for testing.
    pub fn add_at(&mut self, limit: &RateLimit, key: K, cost: u32, at: Instant) -> bool {
