Struct domain::rdata::svcb::value::Ech

source ·
pub struct Ech<Octs: ?Sized>(/* private fields */);
Expand description

The Encrypted Client Hello (ECH) service parameter value.

This value holds the information necessary to connect to the service with Encrypted Client Hello. It contains all this information in wire-format to be used with the TLS ECH extension currently in development as Internet draft draft-ietf-tls-esni.

Implementations§
