Enum ProtocolError 

pub enum ProtocolError {
    PayloadEncoding,
    InvalidReply(String),
    InvalidTimestamp,
    InvalidDuration,
    Compression(String),
}

Wire-level failures that are errors rather than misses.

Variants

PayloadEncoding

A frame’s encoding tag is neither text (0x00) nor binary (0x01).

InvalidReply(String)

The server accepted a command but replied outside the protocol; the text says how, for example a watermark that is not a digit string.

InvalidTimestamp

A stamp is not a nonnegative safe integer, or an invalidation would push its watermark past one.

InvalidDuration

A TTL is not positive, or a TTL or future buffer exceeds 365 days.

Compression(String)

zstd or its configuration failed on the write side; the text is zstd’s error name or the rejected option.

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 Eq for ProtocolError

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.
