Required methods

fn message(&self) -> &str

The primary human-readable error message. Typically one line.

fn details(&self) -> Option<&str>

An optional secondary error message providing more details about the problem, if it was provided by the database. Might span multiple lines.

fn table_name(&self) -> Option<&str>

Currently this method will return None for all backends other than PostgreSQL.

fn column_name(&self) -> Option<&str>

Currently this method will return None for all backends other than PostgreSQL.
