Struct DepsDevClient 

pub struct DepsDevClient { /* private fields */ }

Assembles SupplyChainTrustSignals from deps.dev’s two-call sequence.

Layers its own TTL memo over HttpCache’s reused transport — see the module docs for the caching/failure-handling rationale.

Implementations

impl DepsDevClient

pub fn new(cache: Arc<HttpCache>) -> Self

Creates a client that reuses cache’s HTTP transport for both deps.dev calls, pointed at the real deps.dev API.

pub fn for_test(cache: Arc<HttpCache>, base_url: impl Into<String>) -> Self

Creates a client pointed at base_url instead of the real deps.dev API, for mockito-backed tests.

pub async fn trust_signal( &self, system: &'static str, name: &str, version: &str, ) -> Option<SupplyChainTrustSignal>

Returns the supply-chain trust signal for one resolved (system, name, version), or None when nothing is available to render.

Infallible by construction (FR-006) — every failure degrades to None, memoized under the short error TTL so a transient outage does not re-fire on every hover. A call for a key another concurrent call is already fetching returns None immediately rather than duplicating the fetch (N1) — the caller’s own memo read on its next call picks up the result once the in-flight fetch completes and writes it.

Trait Implementations

impl Debug for DepsDevClient

Manual, non-exhaustive impl: VersionData derives Debug and holds this behind Option<&Arc<DepsDevClient>>, but the memo maps’ entry types have no reason to derive Debug of their own.

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

Formats the value using the given formatter.
