# Enum actix_redis::RespError

[−]

    pub enum RespError {
        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.
