Enum Admission 

#[non_exhaustive]
pub enum Admission {
    Allowed,
    RateLimited,
    ConcurrencyLimited,
    LoadShed,
}

Result of an admission check — whether a request is allowed through.

Stability

This enum is #[non_exhaustive] — new variants may be added in minor releases.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Allowed

Request is allowed to proceed

RateLimited

Request is rate-limited (too many requests per second)

ConcurrencyLimited

Request is concurrency-limited (too many in-flight requests)

LoadShed

Request is load-shed (system is overloaded)

Implementations

impl Admission

pub fn is_allowed(self) -> bool

Returns true if the request is allowed through.

Trait Implementations

impl Clone for Admission

fn clone(&self) -> Admission

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for Admission

impl Debug for Admission

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

Formats the value using the given formatter.

impl Eq for Admission

impl PartialEq for Admission

fn eq(&self, other: &Admission) -> 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.
