Struct libp2p_core::transport::upgrade::Builder
source · pub struct Builder<T> { /* private fields */ }
Expand description
A Builder
facilitates upgrading of a Transport
for use with
a Swarm
.
The upgrade process is defined by the following stages:
authenticate
{1}
-> apply
{*}
-> multiplex
{1}
It thus enforces the following invariants on every transport
obtained from multiplex
:
- The transport must be authenticated and multiplexed.
- Authentication must precede the negotiation of a multiplexer.
- Applying a multiplexer is the last step in the upgrade process.
- The
Transport::Output
conforms to the requirements of aSwarm
, namely a tuple of aPeerId
(from the authentication upgrade) and aStreamMuxer
(from the multiplexing upgrade).

self,
upgrade: U,
) -> Authenticated<AndThen<T, impl FnOnce(C, ConnectedPoint) -> Authenticate<C, U> + Clone>>where

E: Error + 'static,
Upgrades the transport to perform authentication of the remote.
The supplied upgrade receives the I/O resource C
and must
produce a pair (PeerId, D)
, where D
is a new I/O resource.
The upgrade must thus at a minimum identify the remote, which typically
involves the use of a cryptographic authentication protocol in the
context of establishing a secure channel.
§Transitions
- I/O upgrade:
C -> (PeerId, D)
. - Transport output:
C -> (PeerId, D)
