Struct CacheClientConfig 

pub struct CacheClientConfig {
    pub connect_timeout: Duration,
    pub abandon_timeout: Duration,
    pub stall_timeout: Duration,
    pub total_timeout: Duration,
    pub breaker: CircuitBreakerConfig,
}

Tunables for CacheClientStore. Default carries the production values, from_env applies operator overrides, and tests construct one directly (short timeouts, near-zero or very long cooldown) instead of sleeping.

Fields

connect_timeout: Duration

abandon_timeout: Duration

The direct-path race budget: every phase where the cache can lose, which after Phase 0 is all of them. Applied at the header (time-to- headers) phase of the five send() sites.

stall_timeout: Duration

Per-chunk bound on get_ranges’ pull_exact read. Looser than abandon_timeout because a mid-stream abandon re-reads the ranges not yet delivered – a cost knob, not a correctness bound. Also backs the GET /obj response body’s per-frame bound, but not directly: the client’s ClientBuilder::read_timeout is set to stall_timeout + abandon_timeout (looser by a margin), so /ranges’ own explicit pull_exact wrap – set to stall_timeout exactly – is always the one that fires first on a real stall, never read_timeout. Reused as the breaker’s cooldown.

total_timeout: Duration

breaker: CircuitBreakerConfig

Implementations

impl CacheClientConfig

pub fn from_env() -> CacheClientConfig

Apply MICROMEGAS_OBJECT_CACHE_CLIENT_* operator overrides on top of Default. stall_timeout/total_timeout stay fixed named constants (see “The constants that are not env vars”); only the connect budget, abandon budget, and breaker threshold are env-overridable.

Trait Implementations

impl Clone for CacheClientConfig

fn clone(&self) -> CacheClientConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CacheClientConfig

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

Formats the value using the given formatter.

impl Default for CacheClientConfig

fn default() -> CacheClientConfig

Returns the “default value” for a type.
