Enum redis_async::error::Error

pub enum Error {
    Internal(String),
    IO(Error),
    RESP(String, Option<RespValue>),
    Remote(String),
    Connection(ConnectionReason),
    Unexpected(String),
}

Variants

Internal(String)

A non-specific internal error that prevented an operation from completing

IO(Error)

An IO error occurred

RESP(String, Option<RespValue>)

A RESP parsing/serialising error occurred

Remote(String)

A remote error

Connection(ConnectionReason)

Error creating a connection, or an error with a connection being closed unexpectedly

Unexpected(String)

An unexpected error. In this context "unexpected" means "unexpected because we check ahead of time", it used to maintain the type signature of chains of futures; but it occurring at runtime should be considered a catastrophic failure.

If any error is propagated this way that needs to be handled, then it should be made into a proper option.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

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.

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

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

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

pub fn description(&self) -> &str

👎 Deprecated since 1.42.0:

use the Display impl or to_string()

pub fn cause(&self) -> Option<&dyn Error>

👎 Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

impl From<Error> for Error

pub fn from(err: Error) -> Error

Performs the conversion.

impl<T: 'static + Send> From<TrySendError<T>> for Error

pub fn from(err: TrySendError<T>) -> Error

Performs the conversion.
