retrostash-ktor

Ktor HttpClient plugin with parallel semantics to the OkHttp adapter. Targets Android, JVM, iOS, and wasmJs.

Entry points

• RetrostashPlugin — the Ktor client plugin. Install via install(RetrostashPlugin) { store = ...; timeoutMs = ...; logger = ... }.

• RetrostashConfig — plugin configuration.

• RetrostashKtorRuntime — adapter that bridges per-request metadata to the core engine; exposes invalidateTag, invalidateTags.

• RetrostashKtorMetadata and the retrostash, retrostashQuery, retrostashMutate builder extensions for attaching cache metadata to a HttpRequestBuilder.

Notes

Ktor's HttpClient does not ship a built-in HTTP disk cache the way OkHttp does, so the dual-cache footgun documented for the OkHttp adapter does not apply here. Retrostash is the authoritative cache for Ktor consumers.
