Struct BreakerPolicyConfig 

pub struct BreakerPolicyConfig {
    pub window: WindowConfig,
    pub min_request_count: u64,
    pub failure_ratio_percent: u8,
    pub drop_ratio_percent: u8,

}

Advanced breaker policy used by production-oriented breakers.

Fields

window: WindowConfig

Rolling window configuration used for aggregate decisions.

min_request_count: u64

Minimum request count before aggregate failure ratio can open or drop.

failure_ratio_percent: u8

Failure ratio percentage that opens the breaker when enough samples exist.

drop_ratio_percent: u8

Deterministic drop percentage while the rolling window is unhealthy.

half_open_max_calls: u32

Maximum concurrent trial calls in half-open state.

force_pass_interval: Duration

Minimum interval between forced trial calls while open.

sre_rejection_enabled: bool

Enables Google SRE style client-side throttling while closed.

sre_k_millis: u32

SRE throttling multiplier in millis. 1500 means k = 1.5.

sre_protection: u64

Minimum total samples before SRE throttling can reject requests.

Implementations

impl BreakerPolicyConfig

pub fn google_sre() -> Self

Returns a policy using Google SRE style adaptive rejection.

Trait Implementations

impl Clone for BreakerPolicyConfig

fn clone(&self) -> BreakerPolicyConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BreakerPolicyConfig

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

Formats the value using the given formatter.

impl Default for BreakerPolicyConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for BreakerPolicyConfig

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