TLS cipher suite identifiers covering TLS 1.3 mandatory suites and commonly-used TLS 1.2 AEAD suites.

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.

Implementations

impl CipherSuite

pub const ALL: &'static [CipherSuite]

All named cipher suites (excluding CipherSuite::Unknown).

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

Returns the IANA two-byte identifier for this cipher suite.

Returns [0x00, 0x00] for CipherSuite::Unknown.

pub fn from_iana(bytes: [u8; 2]) -> Option<Self>

Try to look up a cipher suite from its IANA two-byte identifier.

pub fn is_tls13(&self) -> bool

Whether this suite belongs to TLS 1.3.

pub fn is_tls12(&self) -> bool

Whether this suite belongs to TLS 1.2.

pub fn is_unknown(&self) -> bool

Whether this is the Unknown catch-all variant.

Trait Implementations

impl Clone for CipherSuite

fn clone(&self) -> CipherSuite

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CipherSuite

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

Formats the value using the given formatter.

impl Display for CipherSuite

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

Formats the value using the given formatter.

impl FromStr for CipherSuite

type Err = TlsError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for CipherSuite

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 PartialEq for CipherSuite

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