Struct RateLimit 

pub struct RateLimit { /* private fields */ }

A request allowance: limit requests per window.

limit is a NonZeroU32 so that a misconfiguration which means “refuse everything” is not expressible by accident. The type has no “unlimited” state either: a caller that genuinely wants no limit should not put this type in the path at all, so “unlimited” can never be the accidental result of a zero that survived a round trip through configuration.

Implementations

impl RateLimit

pub const fn new(limit: NonZeroU32, window: Duration) -> Self

An allowance of limit requests per window.

Panics

If window is zero. A window of zero is a server that refuses everything, and that is not a condition worth discovering from traffic, so it is rejected at construction. limit cannot be zero by type.

pub const fn limit(&self) -> NonZeroU32

Requests permitted per window.

pub const fn window(&self) -> Duration

The width of the window.
