Enum ProtocolError 

#[non_exhaustive]
pub enum ProtocolError {
    Malformed(&'static str),
}

Why a buffer could not be parsed into a command (or reply). A frame that is merely incomplete is not an error: the parsers answer Ok(None) for it.

let e = kevy_resp::parse_command(b"*x\r\n").unwrap_err();
assert_eq!(e.to_string(), "malformed frame: bad multibulk count");

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Malformed(&'static str)

A malformed frame that can never become valid (e.g. bad length prefix).

use kevy_resp::{ProtocolError, parse_command};

let err = parse_command(b"*1\r\n$x\r\n").unwrap_err();
assert!(matches!(err, ProtocolError::Malformed(_)));

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
