Enum HandshakeKind 

#[non_exhaustive]
pub enum HandshakeKind {
    Full,
    FullWithHelloRetryRequest,
    Resumed,
    ResumedWithHelloRetryRequest,
}

Describes which sort of handshake happened.

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.

Full

A full handshake.

This is the typical TLS connection initiation process when resumption is not available, and the initial ClientHello was accepted by the server.

FullWithHelloRetryRequest

A full TLS1.3 handshake, with an extra round-trip for a HelloRetryRequest.

The server can respond with a HelloRetryRequest if the initial ClientHello is unacceptable for several reasons, the most likely being if no supported key shares were offered by the client.

Resumed

A resumed handshake.

Resumed handshakes involve fewer round trips and less cryptography than full ones, but can only happen when the peers have previously done a full handshake together, and then remember data about it.

ResumedWithHelloRetryRequest

A resumed handshake, with an extra round-trip for a HelloRetryRequest.

The server can respond with a HelloRetryRequest if the initial ClientHello is unacceptable for several reasons, but this does not prevent the client from resuming.

Trait Implementations

impl Clone for HandshakeKind

fn clone(&self) -> HandshakeKind

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for HandshakeKind

impl Debug for HandshakeKind

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

Formats the value using the given formatter.

impl PartialEq for HandshakeKind

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