Enum RateLimitUnavailable 

pub enum RateLimitUnavailable {
    FailOpen,
    FailClosed,
    SoftDenyAfterThreshold(u32),
}

Behaviour when the rate-limit store is unavailable (RFC-008 §4).

Variants

FailOpen

Allow the operation to proceed; log the store error internally. Appropriate when rate limiting is a defence-in-depth layer and availability is preferred over strict enforcement.

FailClosed

Deny the operation. Appropriate when rate limiting is a hard requirement and availability is secondary.

SoftDenyAfterThreshold(u32)

Allow until the counter reaches n above the normal threshold, then deny. A compromise for services with intermittent store issues.

Trait Implementations

impl Clone for RateLimitUnavailable

fn clone(&self) -> RateLimitUnavailable

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for RateLimitUnavailable

impl Debug for RateLimitUnavailable

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for RateLimitUnavailable

fn default() -> RateLimitUnavailable

Returns the “default value” for a type.

impl Eq for RateLimitUnavailable

impl PartialEq for RateLimitUnavailable

fn eq(&self, other: &RateLimitUnavailable) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
