Struct PostgresError 

pub struct PostgresError {
    pub sqlstate: Option<String>,
    /* private fields */
}

A Postgres failure that retains its SQLSTATE, so retry decisions are made on the code rather than on rendered text.

SQLSTATE is the documented, stable API; the message is not — it is localised, it embeds user identifiers (a slot literally named orders_is_active matched the old substring rule), and a sqlx/server reword silently removed the restart-race backoff altogether (#654 H8). Carried inside FaucetError::Custom, which exists for exactly this kind of connector-specific wrapping.

Fields

sqlstate: Option<String>

The five-character SQLSTATE, when the server supplied one.

Implementations

impl PostgresError

pub fn new( sqlstate: Option<String>, context: impl Into<String>, message: impl Into<String>, ) -> Self

Build one directly, for callers (and tests) that already know the code.

Trait Implementations

impl Debug for PostgresError

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

Formats the value using the given formatter.

impl Display for PostgresError

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

Formats the value using the given formatter.

impl Error for PostgresError

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.
