The set of cases where we failed to make a connection because we thought the peer was misbehaving.

This is non_exhaustive: we might add or stop using items here in minor versions. We also don’t document what they mean. Generally a user of rustls shouldn’t vary its behaviour on these error codes, and there is nothing it can do to improve matters.

Please file a bug against rustls if you see Error::PeerMisbehaved in the wild.

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.

Trait Implementations

impl Clone for PeerMisbehaved

fn clone(&self) -> PeerMisbehaved

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PeerMisbehaved

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

Formats the value using the given formatter.

impl From<PeerMisbehaved> for Error

fn from(e: PeerMisbehaved) -> Self

Converts to this type from the input type.

impl PartialEq for PeerMisbehaved

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

impl StructuralPartialEq for PeerMisbehaved
