Struct deno_core::JsRuntimeInspector [−][src]
pub struct JsRuntimeInspector { /* fields omitted */ }
Expand description
This structure is used responsible for providing inspector interface
to the JsRuntime
.
It stores an instance of v8::inspector::V8Inspector
and additionally
implements v8::inspector::V8InspectorClientImpl
.
After creating this structure it’s possible to connect multiple sessions to the inspector, in case of Deno it’s either: a “websocket session” that provides integration with Chrome Devtools, or an “in-memory session” that is used for REPL or converage collection.
Implementations
This function blocks the thread until at least one inspector client has established a websocket connection and successfully completed the handshake. After that, it instructs V8 to pause at the next statement.
Obtain a sender for proxy channels.
After a proxy is sent inspector will wait for a “handshake”. Frontend must send “Runtime.runIfWaitingForDebugger” message to complete the handshake.
Create a channel that notifies the frontend when inspector is dropped.
NOTE: Only a single handler is currently available.
Create a local inspector session that can be used on the same thread as the isolate.
Trait Implementations
JsRuntimeInspector
implements a Future so that it can poll for new incoming
connections and messages from the WebSocket server. The Worker that owns
this JsRuntimeInspector
will call this function from Worker::poll()
.
