Struct webpki::DNSNameRef
[−]
[src]
pub struct DNSNameRef<'a>(_);
A reference to a DNS Name suitable for use in the TLS Server Name Indication (SNI) extension and/or for use as the reference hostname for which to verify a certificate.
A DNSNameRef
is guaranteed to be syntactically valid. The validity rules
are specified in RFC 5280 Section 7.2, except that underscores are also
allowed.
Eq
, PartialEq
, etc. are not implemented because name comparison
frequently should be done case-insensitively and/or with other caveats that
depend on the specific circumstances in which the comparison is done.
