Struct CounterKey 

pub struct CounterKey { /* private fields */ }

The complete logical identity of one stored rate-limit counter.

Backends must use both the policy configuration fingerprint and opaque subject key when comparing, ordering, locking, or persisting counters.

Implementations

impl CounterKey

pub const fn new(fingerprint: PolicyFingerprint, subject: SubjectKey) -> Self

Constructs a logical counter key from its fixed-width components.

pub const fn fingerprint(self) -> PolicyFingerprint

Returns the policy configuration fingerprint.

pub const fn subject(self) -> SubjectKey

Returns the opaque subject key.

pub fn to_bytes(self) -> [u8; 64]

Returns the stable fingerprint || subject byte representation.

This fixed-width encoding deliberately has no framing because both components are exactly 32 bytes.

Trait Implementations

impl Clone for CounterKey

fn clone(&self) -> CounterKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for CounterKey

impl Debug for CounterKey

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

impl Eq for CounterKey

impl Hash for CounterKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for CounterKey

fn cmp(&self, other: &CounterKey) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for CounterKey

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for CounterKey

fn partial_cmp(&self, other: &CounterKey) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

Tests less than or equal to (for self and other) and is used by the <= operator.

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

Tests greater than (for self and other) and is used by the > operator.

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

Tests greater than or equal to (for self and other) and is used by the >= operator.
