Struct DatabaseError 

pub struct DatabaseError { /* private fields */ }

A database failure, Error::Database: what the server said (its message and SQLSTATE), or the driver’s description of a failure that is not the server’s.

Its source is the driver’s error (type erased: the driver’s types are not part of this crate’s API outside pg_unstable).

Implementations

impl DatabaseError

pub fn message(&self) -> &str

The server’s message (relation "versions" does not exist), or the driver’s text and its causes when the server said nothing (error connecting to server: ..., error performing TLS handshake: invalid peer certificate: ...).

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

The SQLSTATE the server reported (five characters, e.g. 42P01), if it was the server’s error.

Trait Implementations

impl Debug for DatabaseError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DatabaseError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

The message, then the SQLSTATE in parentheses when there is one.

impl Error for DatabaseError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.
