Function getSynchronizedTypeKeys

This strange piece of code is used to get a runtime array of keys that is guaranteed to be in sync with the keys of the provided interface.

Example

export interface Db2DialectOptions {
  db2Module?: Db2Module;
}

const DIALECT_OPTION_NAMES = getSynchronizedKeys<Db2DialectOptions>({
  // if a key is missing, TypeScript will throw an error
  db2Module: undefined,
});

// Output is ['db2Module']
