Struct c3p0_postgres::deadpool::postgres::tokio_postgres::error::Error

pub struct Error(_);

An error communicating with the Postgres server.

Implementations

impl Error

pub fn into_source(
    self
) -> Option<Box<dyn Error + 'static + Send + Sync, Global>>

Consumes the error, returning its cause.

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.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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
