runWithRequest() function
Runs the given function with request bound to the current async execution context, so any code reached from it (and its asynchronous continuations) can access the in-flight request's metadata via currentMetadata() without threading it through call signatures.
The binding is scoped to the function: it is established for the duration of the call and automatically removed afterwards, which keeps concurrent requests isolated from one another.
Signature:
export declare function runWithRequest<T>(request: IMQRPCRequest, fn: () => T): T;Parameters
