Struct JsonWebToken 

pub struct JsonWebToken<P> { /* private fields */ }

JWT codec backed by the jsonwebtoken crate.

This is the main codec implementation provided by the crate.

Key management

The default constructor uses built-in ES384 development keys. This is convenient for tests or local development.

For persistent sessions across restarts or multiple instances, construct the codec with explicit keys via JsonWebToken::new_with_options.

Implementations

impl<P> JsonWebToken<P>

pub fn new_with_options(options: JsonWebTokenOptions) -> Self

Creates a codec from explicit options.

Use this when you need explicit signing or verification configuration.

pub fn key_id(&self) -> &str

Returns the signing kid used by this codec.

pub fn verification_key_count(&self) -> usize

Returns the number of currently configured verification keys.

pub fn has_verification_key(&self, kid: &str) -> bool

Returns whether a verification key for the given kid exists.

pub fn allows_missing_kid_fallback(&self) -> bool

Returns whether this codec allows verification without kid.

pub fn replace_verification_keys( &self, keys: HashMap<String, DecodingKey>, allow_missing_kid_fallback: bool, )

Atomically replaces all verification keys.

pub fn replace_verification_keys_from_jwks( &self, keys: &[EcP384Jwk], allow_missing_kid_fallback: bool, ) -> Result<()>

Atomically replaces all verification keys from canonical ES384 JWK entries.

Errors

Returns an error when any provided key cannot be converted.

Trait Implementations

impl<P: Clone> Clone for JsonWebToken<P>

fn clone(&self) -> JsonWebToken<P>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<P> Codec for JsonWebToken<P>

where P: Serialize + DeserializeOwned + Clone,

type Payload = P

Type of the payload being encoded/decoded.

fn encode(&self, payload: &Self::Payload) -> Result<Vec<u8>>

Encodes a payload into an opaque, implementation-defined byte vector.

fn decode(&self, encoded_value: &[u8]) -> Result<Self::Payload>

Decodes a previously encoded payload.

impl<P> Default for JsonWebToken<P>

fn default() -> Self

Returns the “default value” for a type.
