sqlx-errors

Map sqlx database errors to typed AppError responses by implementing From<sqlx::Error> for your AppError, converting common variants like RowNotFound and DatabaseError into appropriate HTTP responses.

Prevent leaking raw sqlx error strings to clients by mapping internal sqlx::Error variants to safe AppError responses, using structured logging for internal details while returning generic client-facing messages.

Yes, cross-database error handling uses the DatabaseError trait methods is_unique_violation, is_foreign_key_violation, and is_check_violation to safely classify constraints without relying on database-specific error strings.

Handle sqlx RowNotFound errors in user-facing lookups by using fetch_optional instead of fetch_one, which returns None rather than throwing an error, giving you explicit control over the AppError response.

Log sqlx errors safely by capturing the internal error details in structured logs while returning a generic AppError message to the client, ensuring database constraint violations are classified without leaking raw strings.

Use typed AppError responses instead of raw sqlx errors to standardize HTTP status codes for specific constraint violations and prevent sensitive database schema details from reaching external API clients.
