Diagnostics

Diagnostics is the namespace a plugin or adapter uses to build and narrow the structured errors Kubb collects during a build. Throw or return a Diagnostics.Error instead of a bare Error when you want a stable code, a severity, and a location attached.

Member	Purpose
Diagnostics.Error	Constructs a diagnostic-carrying error with a code, severity, and message
Diagnostics.hasError	Narrows an array of diagnostics to whether any has severity: 'error'
Diagnostics.isProblem	Guards a diagnostic down to the problem kind (as opposed to performance or update)

See the Diagnostics reference for the full list of stable codes Kubb ships with, and how Diagnostics.hasError and Diagnostics.isProblem are used together after a build.
