Decision

Struct Decision 

Source
pub struct Decision { /* private fields */ }
Expand description

The outcome of evaluating one check.

Allowed outcomes report quota remaining after the check and the backend-reported time until the anchored window resets. Denied outcomes carry a Denial.

Implementations§

Source§

impl Decision

Source

pub const fn allowed(limit: u64, remaining: u64, reset_after: Duration) -> Self

Constructs an allowed decision.

Storage backends should pass the remaining quota after consuming the check’s cost. This low-level constructor trusts the backend to ensure remaining <= limit.

Source

pub const fn denied(denial: Denial) -> Self

Constructs a denied decision.

Source

pub const fn is_allowed(&self) -> bool

Returns whether the check was allowed.

Source

pub const fn is_denied(&self) -> bool

Returns whether the check was denied.

Source

pub const fn limit(&self) -> Option<u64>

Returns the configured limit when it is meaningful for this outcome.

Allowed decisions and quota denials have a limit. Storage-capacity denials do not.

Source

pub const fn remaining(&self) -> Option<u64>

Returns the quota remaining after an allowed check.

Source

pub const fn reset_after(&self) -> Option<Duration>

Returns the backend-reported time until an allowed check’s anchored window resets.

Source

pub const fn retry_after(&self) -> Option<Duration>

Returns the backend-reported duration after which a denied check may retry.

Source

pub const fn retry_after_seconds(&self) -> Option<u64>

Returns a whole-second Retry-After value rounded up, if known.

Source

pub const fn denial(&self) -> Option<&Denial>

Returns denial details for a denied check.
