clj-r2dbc.impl.sql.error

R2DBC exception translation utilities for clj-r2dbc.

Provides:
  r2dbc-ex->ex-info - converts R2dbcException to Clojure ex-info with standard keys.
  wrap-error        - wraps a Missionary task, translating R2dbcException on failure.

All R2DBC driver exceptions are mapped to stable :clj-r2dbc/error-category keywords.
Missionary Cancelled is never swallowed.

This namespace is an implementation detail; do not use from application code.

r2dbc-ex->ex-info

(r2dbc-ex->ex-info ex)
Convert an R2dbcException to a Clojure ex-info with standard keys.

Args:
  ex - the R2dbcException to convert.

Returns an ExceptionInfo with:
  :clj-r2dbc/error-category - keyword category (see r2dbc-category).
  :sql-state                - SQL state string from the exception.
  :error-code               - driver-specific error code integer.

The original R2dbcException is set as the cause.

Example:
  (r2dbc-ex->ex-info (R2dbcBadGrammarException. "msg" "42000" 1234 nil))

wrap-error

(wrap-error task)
Wrap a Missionary task, translating any R2dbcException to an ex-info on failure.

Missionary Cancelled is re-thrown immediately and is never translated.
Any other exception passes through unchanged.

Args:
  task - the Missionary task to wrap.

Returns a task that resolves to the same value on success, or rejects with
an ex-info (from r2dbc-ex->ex-info) when an R2dbcException is thrown.

Example:
  (m/? (wrap-error (m/sp (throw (R2dbcTimeoutException. "timed out" "HYT00" 0 nil)))))
