Enum BreakerState 

#[non_exhaustive]
pub enum BreakerState {
    Closed,
    Open,
    HalfOpen,
}

Available on crate feature circuit-breaker only.

The breaker’s current state, as a snapshot.

#[non_exhaustive]: matching should include a wildcard.

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.

Closed

Requests flow to the wrapped limiter; failures are being counted.

Open

Requests are shed immediately; the downstream is being given time.

HalfOpen

A few trial requests are allowed to test whether the downstream recovered.

impl Eq for BreakerState

impl PartialEq for BreakerState

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

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

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