This is a simple convenience method.

pub fn is_closed(&self) -> bool

Determines if the error was associated with closed connection.

pub fn code(&self) -> Option<&SqlState>

Returns the SQLSTATE error code associated with the error.

This is a convenience method that downcasts the cause to a DbError and returns its code.

pub fn unexpected_message() -> Error

Constructs an UnexpectedMessage error.

pub fn parse(e: Error) -> Error
