Struct NamedGroup 

pub struct NamedGroup(pub u16);

The NamedGroup TLS protocol enum. Values in this enum are taken from the various RFCs covering TLS, and are listed by IANA.

This enum is used for recognizing key exchange groups advertised by a peer during a TLS handshake. It is not a list of groups that Rustls supports. The supported groups are determined via the CryptoProvider interface.

Protocol enumerations in rustls are represented with a struct, which contains the numeric value used on the wire (in this case, u16). Each known value has a named const item on this type – this can be used in a match arm or to access the numeric value.

If a known value does not exist for a value you need, you can simply create it locally:

pub const MyValue: NamedGroup = NamedGroup(123);

The Debug impl for this type also looks up and pretty-prints known named items. Unknown values are formatted in hexadecimal.

pub fn to_array(self) -> [u8; 2]

Encode the value as a big-endian byte array.

impl NamedGroup

pub fn key_exchange_algorithm(self) -> KeyExchangeAlgorithm

Return the key exchange algorithm associated with this NamedGroup

pub fn usable_for_version(&self, version: ProtocolVersion) -> bool

Returns whether this NamedGroup is usable for the given protocol version.

Trait Implementations

impl Clone for NamedGroup

fn clone(&self) -> NamedGroup

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NamedGroup

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

Formats the value using the given formatter.

impl From<NamedGroup> for u16

fn from(x: NamedGroup) -> Self

Converts to this type from the input type.

impl From<u16> for NamedGroup

fn from(x: u16) -> Self

Converts to this type from the input type.

impl Hash for NamedGroup

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,

impl PartialEq for NamedGroup

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