Struct Error

pub struct Error(/* private fields */);

public facing error type. providing basic format and display based error handling.

for typed based error handling runtime type cast is needed with the help of other public error types offered by this module.

Example

use xitca_postgres::error::{DriverDown, Error};

fn is_driver_down(e: Error) -> bool {
    // downcast error to DriverDown error type to check if client driver is gone.
    e.downcast_ref::<DriverDown>().is_some()
}

Implementations

impl Error

pub fn is_driver_down(&self) -> bool

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Deref for Error

type Target = dyn Error + Sync + Send

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl DerefMut for Error

fn deref_mut(&mut self) -> &mut Self::Target

Mutably dereferences the value.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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
