Enum ProtocolError 

pub enum ProtocolError {
    Incomplete,
    UnexpectedEof,
    InvalidPrefix(u8),
    InvalidInteger,
    InvalidFrameLength(i64),
    InvalidCommandFrame(String),
    WrongArity(String),
    NestingTooDeep(usize),
    TooManyElements(usize),
    BulkStringTooLarge(usize),
}

Errors that can occur when parsing the RESP3 wire format.

Variants

Incomplete

The input buffer doesn’t contain a complete frame yet. The caller should read more data and try again.

UnexpectedEof

Reached end of input unexpectedly while parsing a frame.

InvalidPrefix(u8)

The first byte of a frame didn’t match any known RESP3 type prefix.

InvalidInteger

Failed to parse an integer value from the frame content.

InvalidFrameLength(i64)

A bulk string or array declared an invalid length (e.g. negative).

InvalidCommandFrame(String)

Expected an array frame for a command, but got something else.

WrongArity(String)

Command received with the wrong number of arguments.

NestingTooDeep(usize)

The frame exceeds the maximum nesting depth.

TooManyElements(usize)

An array or map declares more elements than the allowed maximum.

BulkStringTooLarge(usize)

A bulk string exceeds the maximum allowed length.

Trait Implementations

impl Clone for ProtocolError

fn clone(&self) -> ProtocolError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ProtocolError

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

Formats the value using the given formatter.

impl Display for ProtocolError

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

Formats the value using the given formatter.

impl Error for ProtocolError

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

fn provide<'a>(&'a self, request: &mut Request<'a>)

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

Provides type-based access to context intended for error reports.

impl PartialEq for ProtocolError

fn eq(&self, other: &ProtocolError) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
