Errors

The TypeScript implementation exports three public error classes:

• CSDBError: base class for CSDB library errors.
• ValidationError: invalid file structure, metadata, schema, values, constraints, or relationships.
• SQLError: unsupported or invalid SQL syntax.

Python should expose the same hierarchy:

class CSDBError(Exception): ...
class ValidationError(CSDBError): ...
class SQLError(CSDBError): ...

Typical handling:

try {
  db.validate();
} catch (error) {
  if (error instanceof ValidationError) {
    console.error(error.message);
  }
}
