Struct RateLimitConfig 

pub struct RateLimitConfig {
    pub enabled: bool,
    pub per_user_rpm: u32,
    pub per_ip_rpm: u32,
    pub per_route_rpm: u32,

    pub redis_enabled: bool,
    pub failure_mode: RateLimitFailureMode,
    pub strict_routes: Vec<String>,
}

Rate limiting configuration

Supports both Redis-backed (distributed) and in-memory (single instance) rate limiting. Rate limits can be configured per authenticated user, per IP address, and per specific route patterns.

Example Configuration

[security.rate_limit]
enabled = true
per_user_rpm = 120           # 120 requests per minute for authenticated users
per_ip_rpm = 60              # 60 requests per minute per IP address
per_route_rpm = 30           # 30 requests per minute for specific routes (e.g., auth)
window_secs = 60             # Rate limit window (60 seconds)
redis_enabled = true         # Use Redis for distributed rate limiting
failure_mode = "closed"      # Deny on rate limit errors (strict)

Fields

enabled: bool

Enable rate limiting middleware

per_user_rpm: u32

Requests per minute per authenticated user

per_ip_rpm: u32

Requests per minute per IP address (for anonymous requests)

per_route_rpm: u32

Requests per minute for specific routes (e.g., auth endpoints)

window_secs: u64

Rate limit window in seconds

redis_enabled: bool

Use Redis for distributed rate limiting (requires cache feature) Falls back to in-memory if Redis is unavailable

failure_mode: RateLimitFailureMode

Failure mode when rate limit backend fails

• Closed: Deny requests when rate limiting fails (strict, production)
• Open: Allow requests when rate limiting fails (permissive, development)

strict_routes: Vec<String>

Route patterns that should use stricter rate limits (e.g., "/login", "/register")
