Enum SvcParam 

#[non_exhaustive]
pub enum SvcParam {
    Mandatory(Box<[SvcParamKey]>),
    Alpn(AlpnList),
    NoDefaultAlpn,
    Port(u16),
    Ipv4Hint(Box<[Ipv4Addr]>),
    Ech(Bytes),

    Unknown {

}

Available on crate features dns and std only.

A decoded service binding parameter.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Mandatory(Box<[SvcParamKey]>)

Keys that a client must understand in order to use this record.

Alpn(AlpnList)

ALPN protocol identifiers, each containing between 1 and 255 octets.

NoDefaultAlpn

Indicates that the protocol mapping’s default ALPN set is unsupported.

Port(u16)

TCP or UDP port for the alternative endpoint.

Ipv4Hint(Box<[Ipv4Addr]>)

IPv4 address hints.

Ech(Bytes)

An RFC 9848 ECHConfigList, including its redundant length prefix.

DNS validates the list framing but leaves version-specific ECHConfig interpretation to TLS.

Ipv6Hint(Box<[Ipv6Addr]>)

IPv6 address hints.

Unknown

A parameter whose key or wire format Rama does not yet understand.

Fields

key: SvcParamKey

Numeric service parameter key.

value: Bytes

Uninterpreted wire-format value.
