Struct MethodAwareRateLimiter 

pub struct MethodAwareRateLimiter { /* private fields */ }

A method-aware rate limiter that automatically looks up CU costs per RPC method.

Wraps a TokenBucket with a CuCostTable so callers only need to supply the method name — the correct compute-unit cost is resolved internally.

Implementations

impl MethodAwareRateLimiter

pub fn new(config: RateLimiterConfig, cost_table: CuCostTable) -> Self

Create a new method-aware rate limiter.

pub fn try_acquire_method(&self, method: &str) -> bool

Acquire tokens for a specific RPC method, using its CU cost.

Returns true if the method’s cost was successfully consumed from the bucket, false if the bucket has insufficient tokens (rate limited).

pub fn wait_time_for_method(&self, method: &str) -> Duration

Wait time before the given method can be called.

pub fn bucket(&self) -> &TokenBucket

Access the underlying bucket for manual control.
