"Perform an asynchronous diagnostic request for the current
buffer.
CALLBACK is called with at least one argument, a symbol
representing the status of the request. Depending on the status
more argument are provided. Possible values are explained below:
- success
When quering the diagnostics work, the additional argument is a
list of diagnostic object, diagnostics fields can be queried
with the functions `irony-diagnostics-<xxx>'.
- error
Retrieving the diagnostics wasn't possible. A string explaining
the reason is passed as a second argument.
- cancelled
Retrieving the diagnostics was cancelled, e.g: because the
buffer has changed since the beginning of the request, and as
such the diagnostics are considered no longer relevant. A
reason string is passed as a second argument."
