REST resilience middleware configuration.

Fields

breaker_enabled: bool

Whether route-level circuit breaking is enabled.

breaker_failure_threshold: u32

Consecutive failures that open a route breaker.

breaker_reset_timeout: Duration

Time before an open breaker allows a half-open trial call.

breaker_sre_enabled: bool

Whether the route breaker uses Google SRE style adaptive rejection.

breaker_sre_k_millis: u32

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

breaker_sre_protection: u64

Minimum total samples before SRE breaker rejection can start.

max_concurrency: Option<usize>

Optional maximum number of in-flight requests.

request_timeout: Option<Duration>

Optional timeout overriding RestConfig::timeout for the default stack.

shedding_enabled: bool

Whether adaptive request shedding is enabled.

shedding_max_in_flight: Option<usize>

Maximum in-flight requests used by the adaptive shedder.

shedding_min_request_count: u64

Minimum request samples before latency-based shedding can reject.

shedding_max_latency: Duration

Average latency threshold used by adaptive shedding.

shedding_cpu_threshold_millis: u32

CPU usage threshold used by adaptive shedding, where 1000 means 100%.

shedding_cool_off: Duration

Cool-off duration after a recent adaptive shedder drop.

shedding_window_buckets: usize

Number of buckets used by adaptive shedder rolling windows.

shedding_window_bucket_duration: Duration

Duration represented by each adaptive shedder bucket.

Implementations

impl RestResilienceConfig

pub fn production_defaults() -> Self

Returns a production-oriented resilience profile for production services.

pub fn go_zero_defaults() -> Self

👎Deprecated:

use production_defaults instead

Returns a production-oriented resilience profile.

Trait Implementations

impl Clone for RestResilienceConfig

fn clone(&self) -> RestResilienceConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for RestResilienceConfig

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

Formats the value using the given formatter.

impl Default for RestResilienceConfig

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for RestResilienceConfig

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