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 hint(&self) -> Option<&str>[−]

An optional suggestion of what to do about the problem, if one was provided by the database.

fn table_name(&self) -> Option<&str>[−]

The name of the table the error was associated with, if the error was associated with a specific table and the backend supports retrieving that information.

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

fn column_name(&self) -> Option<&str>[−]

The name of the column the error was associated with, if the error was associated with a specific column and the backend supports retrieving that information.

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

fn constraint_name(&self) -> Option<&str>[−]

The constraint that was violated if this error is a constraint violation and the backend supports retrieving that information.

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