Variants

Mandatory(Vec<u16>)

Mandatory keys that must be understood.

Alpn(Vec<String>)

Application-Layer Protocol Negotiation.

NoDefaultAlpn

No default ALPN (empty value).

Port(u16)

Port number.

Ipv4Hint(Vec<Ipv4Addr>)

IPv4 address hints.

Ech(Vec<u8>)

Encrypted Client Hello.

Ipv6Hint(Vec<Ipv6Addr>)

IPv6 address hints.

Unknown

Unknown parameter.

Fields

key: u16

value: Vec<u8>

Implementations

impl SvcParam

pub fn parse(key: u16, data: &[u8]) -> Result<Self, FieldError>

Parse a single SvcParam from wire format.

pub fn key(&self) -> u16

Get the key for this parameter.

pub fn build_value(&self) -> Vec<u8>

Serialize the parameter value (without key and length header).

pub fn build(&self) -> Vec<u8>

Build the complete key-value pair (key + length + value).

pub fn parse_all(data: &[u8]) -> Result<Vec<Self>, FieldError>

Parse all SvcParams from wire format.

Trait Implementations

impl Clone for SvcParam

fn clone(&self) -> SvcParam

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SvcParam

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

Formats the value using the given formatter.

impl PartialEq for SvcParam

fn eq(&self, other: &SvcParam) -> 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.
