Implementations

impl Algorithm

pub fn as_str(&self) -> &str

Returns the algorithm as a string.

For unknown algorithms, this returns a static “unknown” string. Use [Algorithm::to_string()] to get the actual algorithm name for unknown variants.

pub fn is_unknown(&self) -> bool

Returns true if this is an unknown/unrecognized algorithm.

pub fn is_signing(&self) -> bool

Returns true if this is a signing algorithm.

Unknown algorithms return false since their purpose cannot be determined.

pub fn is_key_encryption(&self) -> bool

Returns true if this is a key encryption algorithm.

Unknown algorithms return false since their purpose cannot be determined.

Trait Implementations

impl Clone for Algorithm

fn clone(&self) -> Algorithm

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Algorithm

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Algorithm

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Algorithm

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

Formats the value using the given formatter.

impl FromStr for Algorithm

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

Parses an algorithm string.

Per RFC 7517, unknown algorithm values are accepted and stored as Unknown. This function never fails - unrecognized values become Algorithm::Unknown(s).

type Err = Infallible

The associated error which can be returned from parsing.

impl Hash for Algorithm

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 Algorithm

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

impl Serialize for Algorithm

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>

where S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Algorithm

impl StructuralPartialEq for Algorithm
