Used to create a new CertifiedKeysWatched. If you want to resolve a wildcard certificate, you
need to specify it for each SNI. It does not resolve SNIs like *.example.com, only absolute
ones.
A TLS Key / Certificate combination created from files. The files are automatically watched and
the internal TLS data will be rebuilt automatically, if a new matching key + cert has been
found. This makes any server using rustls capable of hot-reloading certificates without any
other modification.
Holds multiple certificate bundles and resolves them depending on the SNI from the
ClientHello. Does not dynamically resolve wildcard certificates. You need to add them for
each SNI you want to use it with.
