Struct CircuitBreakerConfig 

#[non_exhaustive]
pub struct CircuitBreakerConfig {
    pub failure_threshold: usize,
    pub failure_window_ms: u64,
    pub reset_timeout_ms: u64,
}

Configuration for a circuit breaker.

Marked #[non_exhaustive] so future minor releases can add new tuning knobs without breaking callers. Construct via CircuitBreakerConfig::default then mutate the fields you care about.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

failure_threshold: usize

Number of failures required to open the circuit

failure_window_ms: u64

Time window in milliseconds to count failures

reset_timeout_ms: u64

Time in milliseconds that the circuit stays open before trying again

Implementations

impl CircuitBreakerConfig

pub fn new( failure_threshold: usize, failure_window_ms: u64, reset_timeout_ms: u64, ) -> Self

Construct a CircuitBreakerConfig from its three core knobs.

Provided so external callers (tests, custom circuit-breaker wiring) can build the struct without depending on its field list, which may grow over the 1.x line. For tuning only a subset, start from Self::default and use the with_* builder methods.

pub fn with_failure_threshold(self, threshold: usize) -> Self

Override the failure-count threshold.

pub fn with_failure_window_ms(self, window_ms: u64) -> Self

Override the failure-counting window in milliseconds.

pub fn with_reset_timeout_ms(self, reset_ms: u64) -> Self

Override the reset-timeout in milliseconds.

Trait Implementations

impl Clone for CircuitBreakerConfig

fn clone(&self) -> CircuitBreakerConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for CircuitBreakerConfig

fn default() -> Self

Returns the “default value” for a type.
