Struct domain::rdata::svcb::value::NoDefaultAlpn

source ·
pub struct NoDefaultAlpn;
Expand description

A signal to not include the service’s default ALPNs in the ALPN set.

For each service that uses SVCB, a set of default Alpn protocols is defined. This set will be included even if they are not explicitely provided via the ALPN value. The no-default-alpn value can be used to signal that they should not be included.

This value is always empty.
