Struct RateLimitConfig 

pub struct RateLimitConfig {
    pub requests_per_period: u32,
    pub period_secs: u64,
    pub burst_size: u32,
    pub enabled: bool,
}

Rate limiting configuration

Fields

requests_per_period: u32

Maximum requests per period

period_secs: u64

Period duration in seconds

burst_size: u32

Burst size (max requests at once)

enabled: bool

Whether rate limiting is enabled

Implementations

impl RateLimitConfig

pub fn from_env() -> Self

Create configuration from environment variables

Environment variables:

• RATE_LIMIT_ENABLED: Enable/disable rate limiting (default: true)
• RATE_LIMIT_REQUESTS: Max requests per period (default: 600)
• RATE_LIMIT_PERIOD_SECS: Period in seconds (default: 60)
• RATE_LIMIT_BURST: Burst size (default: 50)

pub fn replenish_period(&self) -> Duration

The interval at which governor replenishes one request cell.

Governor is configured by period per cell, not by requests per period. Converting with requests_per_period / period_secs in integer arithmetic silently floors the budget — the 100-per-60s default became 1 request per second, a 40% cut, and any budget under one request per second collapsed to the same 1/s floor. Dividing in milliseconds keeps the configured rate.

Returns

The delay between replenished cells; never zero, so governor always has a valid period even for an absurdly large requests_per_period.

pub fn validate(&self) -> Result<(), String>

Validate configuration values
