Enum Error 

pub enum Error {
    Protocol(String),
    Decode(String),
    Encode(String),
    Server(Box<DbError>),
    Auth(String),
}

Errors that can occur while speaking the PostgreSQL wire protocol.

Variants

Protocol(String)

The server sent a message we did not expect in this state.

Decode(String)

A message could not be decoded.

Encode(String)

A message could not be encoded.

Server(Box<DbError>)

The server reported an error.

Boxed to keep Error (and therefore every Result<T, Error>) small; DbError itself is ~250 bytes.

Auth(String)

Authentication failed.

Trait Implementations

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.

impl From<DbError> for Error

fn from(err: DbError) -> Self

Converts to this type from the input type.
