Struct domain::rdata::rfc1035::Null

pub struct Null<Octets> { /* fields omitted */ }

Null record data.

Null records can contain whatever data. They are experimental and not allowed in master files.

The Null record type is defined in RFC 1035, section 3.3.10.

The raw content of the record.

impl<Octets: AsRef<[u8]>> Null<Octets>

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool
