Module inspector 

Inspector capture types — ConsoleEntry, NetworkEntry, ring buffer + level/status enums.

Engine implementations capture these in always-on ring buffers (bounded; FIFO eviction). The agent reads them via the vs_inspect primitive (M5.7 PR2+).

WebKit Inspector protocol is internal only — it never appears on the agent-facing wire. See ADR 0008.

Structs

ConsoleEntry

One captured console event.

CookieEvent

Cookie store change event captured by Engine::cookie_events. macOS uses WKHTTPCookieStoreObserver, Linux uses the WebKitCookieManager::changed signal; both diff snapshots to produce per-cookie Added/Removed events. Windows currently has no observer in webview2-com, so the engine reports inspector_cookie_events = false and the primitive returns ENGINE_UNSUPPORTED.

DomDetail

Detail returned by Engine::dom: outer HTML + computed-style pairs for one ref.

Header

One request/response header pair, captured for vs_inspect request.

NetworkEntry

One captured network event.

PerformanceMetrics

Web Vitals + heap + DOM-stat block returned by Engine::performance. Floats use 2 decimals on the wire; missing metrics are emitted as 0 rather than dropped (keeps the line shape stable).

RequestDetail

Full detail for one captured network request — headers + bodies for both the request and response. Returned by crate::Engine::request_detail when the agent calls vs_inspect request <id>.

RingBuffer

Bounded FIFO ring buffer for inspector captures. Adding to a full buffer evicts the oldest entry. Reads return a snapshot in chronological order (oldest first).

ScriptEntry

One loaded script in Engine::scripts.

ScriptSource

Source of one script (returned by Engine::script_source).

StorageEntry

One entry returned by Engine::storage. Cookies use the optional flag fields; key/value stores use only key and value; IndexedDB uses key (db name) and value (version + object store names joined). The agent doesn’t need a sum type — a uniform shape keeps the wire format simple.

Enums

ConsoleLevel

Console levels observable by vs_inspect console. Mirrors the browser’s console.<level>(...) family plus the synthetic error level we use for uncaught exceptions and unhandled rejections.

CookieAction

EvalResult

Result of Engine::eval_js. The Ok variant carries a JSON- serialized value (or empty for undefined/null); errors are distinguished by kind so the agent can react differently to a thrown exception vs. a SyntaxError vs. a binding/IO failure.

NetworkStatus

Status of a captured network request.

ScriptState

StorageScope

Storage scope for Engine::storage.

Constants

DEFAULT_BUFFER_CAPACITY

Default ring-buffer capacity per kind, per page. Configurable via Daemon::with_inspector_buffer_capacity.
