The SVC Param section of the SVCB DNS RR type. RFC 9460.

Known parameters are defined as variants of this enum and properly parsed. Unknown parameters are stored as Self::Unknown variant.

Variants

Mandatory(BTreeSet<u16>)

Mandatory keys in this RR. Key Code 0.

Alpn(Vec<CharacterString<'a>>)

Additional supported protocols. Key Code 1.

NoDefaultAlpn

No support for default protocol. Key Code 2.

Port(u16)

Port for alternative endpoint. Key Code 3.

Ipv4Hint(Vec<u32>)

IPv4 address hints. Key Code 4.

Ech(Cow<'a, [u8]>)

Encrypted ClientHello (ECH) configuration. Key Code 5.

Ipv6Hint(Vec<u128>)

IPv6 address hints. Key Code 6.

InvalidKey

Reserved for invalid keys. Key Code 65535.

Unknown(u16, Cow<'a, [u8]>)

Unknown key format.

Implementations

impl SVCParam<'_>

pub fn key_code(&self) -> u16

Returns the key code of the parameter

pub fn into_owned<'b>(self) -> SVCParam<'b>

Transforms the inner data into its owned

Trait Implementations

impl<'a> Clone for SVCParam<'a>

fn clone(&self) -> SVCParam<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<'a> Debug for SVCParam<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'a> Hash for SVCParam<'a>

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl<'a> PartialEq for SVCParam<'a>

fn eq(&self, other: &SVCParam<'a>) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
