Enum ProtocolErrorKind 

#[non_exhaustive]
pub enum ProtocolErrorKind {
    Malformed,
    Unsupported,
    Timeout,
    Unauthorized,
    Other,
}

Programmatic classification for StreamError::Protocol.

Lets callers branch on what kind of protocol failure occurred without string-matching the detail message (e.g. retry on Timeout, drop the connection on Malformed).

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

The peer sent bytes that violate the wire format.

Unsupported

A required feature/codec/version is not supported.

Timeout

The operation exceeded its deadline.

Unauthorized

Authentication or stream-key authorization failed.

Other

Anything not covered above.

Trait Implementations

impl Clone for ProtocolErrorKind

fn clone(&self) -> ProtocolErrorKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ProtocolErrorKind

impl Debug for ProtocolErrorKind

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

Formats the value using the given formatter.

impl Eq for ProtocolErrorKind

impl PartialEq for ProtocolErrorKind

fn eq(&self, other: &ProtocolErrorKind) -> 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.
