Enum PgWireError 

pub enum PgWireError {
    Io(String),
    Protocol(String),
    Server(String),
    Auth(String),
    Tls(String),
    Task(String),
    Internal(String),
}

Error type for all pgwire-replication operations.

Variants

Io(String)

I/O error (network, file system).

Note: std::io::Error is not Clone, so we store the message.

Protocol(String)

Protocol error - malformed message or unexpected response.

Server(String)

Server error - PostgreSQL returned an error response.

The message typically includes SQLSTATE code.

Auth(String)

Authentication error - wrong credentials or unsupported method.

Tls(String)

TLS error - handshake failure, certificate validation, etc.

Task(String)

Task error - worker panicked or terminated unexpectedly.

Internal(String)

Internal error - bug in the library.

Implementations

impl PgWireError

pub fn is_io(&self) -> bool

Returns true if this is an I/O error.

pub fn is_server(&self) -> bool

Returns true if this is a server error.

pub fn is_auth(&self) -> bool

Returns true if this is an authentication error.

pub fn is_tls(&self) -> bool

Returns true if this is a TLS error.

pub fn is_transient(&self) -> bool

Returns true if this error is likely transient and retryable.

Transient errors include I/O errors and task errors. Non-transient errors (auth, server, protocol) typically require configuration changes.

Trait Implementations

impl Clone for PgWireError

fn clone(&self) -> PgWireError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PgWireError

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

Formats the value using the given formatter.

impl Display for PgWireError

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

Formats the value using the given formatter.

impl Error for PgWireError

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.

impl From<Error> for PgWireError

fn from(err: Error) -> Self

Converts to this type from the input type.
