gno.land - /r/moul/x/daily/ratelimitdemo/v0

Overview

Package ratelimitdemo is a small on-chain demo of the token-bucket rate limiter provided by the p/moul/x/daily/ratelimit(/p/moul/x/daily/ratelimit/v0) library.

It holds a single package-level ratelimit.Limiter and wires it to the chain: the tick is runtime.ChainHeight() and each caller is keyed by its address (unsafe.PreviousRealm().Address()). It contains no limiter logic of its own — refill/consume math all lives in the library.

Function

Allow


              func Allow(cur realm) bool

Allow consumes one token for the calling realm/user at the current block height and reports whether the request is permitted. Returns false (and consumes nothing) when the caller's bucket is empty.
