JWK parameters defined at https://datatracker.ietf.org/doc/html/rfc7517#section-4

Fields

kid: Option<String>

ID of the key

pk_use: Option<PKUse>

The intended use of the public key

key_ops: Option<Vec<KeyOps>>

The “key_ops” (key operations) parameter identifies the operation(s) for which the key is intended to be used The “use” and “key_ops” JWK members SHOULD NOT be used together; however, if both are used, the information they convey MUST be consistent. Applications should specify which of these members they use, if either is to be used by the application.

alg: Option<Algorithm>

The algorithm intended to be used

x5u: Option<String>

X.509 Public key cerfificate URL.

x5c: Option<Vec<String>>

X.509 public key certificate chain.

x5t: Option<String>

X.509 Certificate thumbprint.

key_params: JwkAlgorithmParameters

Trait Implementations

impl Clone for Jwk

fn clone(&self) -> Jwk

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Jwk

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Jwk

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Jwk

fn eq(&self, other: &Jwk) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for Jwk

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 Jwk
