Struct toluol::DnsFlags

pub struct DnsFlags {
    pub flags: u16,
}

Represents the flags of a DnsHeader.

Fields

flags: u16

Implementations

impl DnsFlags

pub fn new(aa: bool, tc: bool, rd: bool, ra: bool, ad: bool, cd: bool) -> Self

Creates a DnsFlags struct from booleans. The meaning of the flags is as follows:

• aa: authoritative answer (valid in responses only)
• tc: truncated (set on all truncated messages except last one)
• rd: recursion desired (copied in answer if supported and accepted)
• ra: valid in responses, indicating recursive query support in the name server
• ad: if set in query: indicates interest in the ad bit of the upcoming response; if set in response: indicates that the resolver side considers all RRsets in the Answer section and relevant negative response RRs in the Authority section to be authentic.
• cd: disable signature validation in a security-aware name server’s processing of a particular query

pub fn from_flags(flags: u16) -> Self

Creates a DnsFlags struct from bitflags as they would appear in the second 16-octet line of a DnsHeader.

pub fn as_flags(&self) -> u16

Returns a u16 representing bitflags as they would appear in the second 16-octet line of a DnsHeader.

pub fn aa(&self) -> bool

Whether the aa flag is set.

pub fn tc(&self) -> bool

Whether the tc flag is set.

pub fn rd(&self) -> bool

Whether the rd flag is set.

pub fn ra(&self) -> bool

Whether the ra flag is set.

pub fn ad(&self) -> bool

Whether the ad flag is set.

pub fn cd(&self) -> bool

Whether the cd flag is set.
