Struct WeightRateLimiter 

pub struct WeightRateLimiter { /* private fields */ }

Weight-based rate limiter for Binance API.

Tracks API usage based on response headers and provides throttling recommendations to avoid hitting rate limits.

Implementations

impl WeightRateLimiter

pub fn new() -> Self

Creates a new rate limiter with default limits.

pub fn with_limits( weight_limit_1m: u64, order_limit_10s: u64, order_limit_1d: u64, ) -> Self

Creates a new rate limiter with custom limits.

Arguments

• weight_limit_1m - Weight limit per minute
• order_limit_10s - Order limit per 10 seconds
• order_limit_1d - Order limit per day

pub fn update(&self, info: RateLimitInfo)

Updates the rate limiter with information from response headers.

Arguments

• info - Rate limit information extracted from headers

pub fn set_ip_banned(&self, duration: Duration)

Sets the IP ban duration.

Arguments

• duration - Duration of the IP ban

pub fn is_ip_banned(&self) -> bool

Returns true if the IP is currently banned.

pub fn should_throttle(&self) -> bool

Returns true if we should throttle requests.

Throttling is recommended when:

• We’re in a Retry-After period
• Weight usage exceeds 80% of the limit
• Order count exceeds 80% of the limit
• IP is banned

pub fn wait_duration(&self) -> Option<Duration>

Returns the recommended wait duration before making the next request.

Returns None if no waiting is needed.

pub fn used_weight(&self) -> u64

Returns the current used weight.

pub fn weight_limit(&self) -> u64

Returns the weight limit.

pub fn order_count_10s(&self) -> u64

Returns the current order count (10s window).

pub fn order_count_1d(&self) -> u64

Returns the current order count (daily).

pub fn order_limit_1d(&self) -> u64

Returns the order limit per day.

pub fn weight_usage_ratio(&self) -> f64

Returns the weight usage percentage (0.0 to 1.0).

pub fn reset(&self)

Resets all counters.

This should be called when the rate limit window resets.

Trait Implementations

impl Default for WeightRateLimiter

fn default() -> Self

Returns the “default value” for a type.
