Struct RateLimitConfig 

pub struct RateLimitConfig {
    pub limiter: Arc<dyn RateLimiter + Send + Sync>,
    pub key_extractor: KeyExtractor,
    pub exclude_paths: Vec<String>,
    pub key_prefix: String,
}

RateLimit 中间件配置

必须通过 RateLimitConfig::new() 构造，传入一个 RateLimiter 实例（用 Arc 包裹）。 可通过 with_* 链式 builder 方法配置 Key 提取策略、排除路径、Key 前缀。

Fields

limiter: Arc<dyn RateLimiter + Send + Sync>

限流器实例（Arc<dyn RateLimiter + Send + Sync> 共享）

key_extractor: KeyExtractor

Key 提取策略（默认 Ip）

exclude_paths: Vec<String>

排除路径（不进行限流，复用 crate::middleware::auth::is_route_allowed 匹配）

key_prefix: String

Key 前缀（用于区分不同限流场景，如 "login" / "api" / "sms"）

Implementations

impl RateLimitConfig

pub fn new(limiter: Arc<dyn RateLimiter + Send + Sync>) -> Self
