Struct CacheConfig 

pub struct CacheConfig {
    pub enabled: bool,
    pub fetch_timeout_secs: u64,
    pub max_concurrent_fetches: usize,
}

Configuration for HTTP caching behavior.

Controls cache settings for registry requests. The cache uses ETag and Last-Modified headers for validation, minimizing network traffic.

Defaults

• enabled: true
• fetch_timeout_secs: 10 (10 seconds per package)
• max_concurrent_fetches: 20 (20 concurrent requests)

Examples

use deps_lsp::config::CacheConfig;

let config = CacheConfig {
    enabled: true,
    fetch_timeout_secs: 5,
    max_concurrent_fetches: 20,
};

assert_eq!(config.fetch_timeout_secs, 5);

Fields

enabled: bool

Whether deps_core::cache::HttpCache’s entry map is used at all (issue #482): false bypasses it entirely (fetch fresh every time, never store).

Offline override: while network.offline (see NetworkConfig::offline) is set, this flag’s false value is overridden and treated as true — otherwise a warm entry fetched before going offline could never survive an online→offline transition, since nothing would have been stored while online in the first place.

Maven exception: deps-maven’s peek_cached-based stale-data fallback (crates/deps-maven/src/registry.rs) behaves differently from every other ecosystem under enabled: false, which has no equivalent second-layer fallback to diverge on. This only “always misses” for a process that started cold with the flag already off — peek_cached reads the entry map directly and set_cache_enabled never clears it, so a live true -> false toggle leaves every already-stored entry servable through this fallback indefinitely.

fetch_timeout_secs: u64

Timeout for fetching a single package’s versions (default: 10 seconds)

max_concurrent_fetches: usize

Maximum concurrent package fetches (default: 20)
