Type Alias HookError

pub type HookError = HookError<Error>;

Type alias for using deadpool::managed::HookError with tokio_postgres.

Aliased Type

enum HookError {
    Continue(Option<HookErrorCause<Error>>),
    Abort(HookErrorCause<Error>),
}

Variants

Continue(Option<HookErrorCause<Error>>)

This variant can be returned by hooks if the object should be discarded but the operation should be continued.

Abort(HookErrorCause<Error>)

This variant causes the object to be discarded and aborts the operation.

Implementations

impl<E> HookError<E>

pub fn cause(&self) -> Option<&HookErrorCause<E>>

Get optional cause of this error

Trait Implementations

impl<E> Debug for HookError<E>

where E: Debug,

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

Formats the value using the given formatter.

impl<E> Display for HookError<E>

where E: Display,

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

Formats the value using the given formatter.

impl<E> Error for HookError<E>

where E: Error + 'static,

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
