pub trait CacheClient {
// Required method
fn probe(&self, key: &CacheKey) -> CacheOutcome;
// Provided method
fn probe_batch(&self, keys: &[CacheKey]) -> CacheReport { ... }
}Expand description
Typed cache client. New backends (cachix, R2, S3, IPFS, …)
implement this trait + plug into the engine via gen_config.
Required Methods§
Sourcefn probe(&self, key: &CacheKey) -> CacheOutcome
fn probe(&self, key: &CacheKey) -> CacheOutcome
Probe a single cache key. Implementations MUST NOT panic;
transport-level errors land as Miss { TransportError }.
Provided Methods§
Sourcefn probe_batch(&self, keys: &[CacheKey]) -> CacheReport
fn probe_batch(&self, keys: &[CacheKey]) -> CacheReport
Probe a batch of keys. Default impl loops probe — override
for parallel/HTTP-pipelined implementations.
Dyn Compatibility§
This trait is dyn compatible.
In older versions of Rust, dyn compatibility was called "object safety".
