Struct Budget 

pub struct Budget {
    pub key: String,
    pub capacity: f64,
    pub refill_per_sec: f64,
    pub cost: f64,
    pub daily_limit: Option<u64>,
}

The budget a single request spends against, as the router names it.

Fields

key: String

Identifies the upstream (and the API key within it), e.g. "dexscreener" or "rpc:3f9a…". The token-bucket row and the daily quota counter are keyed by exactly this string.

capacity: f64

Token-bucket size: the burst the key may spend at once, and the level every bucket refills toward.

refill_per_sec: f64

Sustained refill rate, tokens per second.

cost: f64

Tokens this one request spends. 1.0 is a plain request; heavier endpoints can charge more. A cost above capacity can never be served and reports exhausted with the wait until a full bucket would cover it.

daily_limit: Option<u64>

Per-UTC-day request quota, counted through Usage with Period::Day. None is untracked: no quota, no database write.
