Struct ContinuityTokenSigner 

pub struct ContinuityTokenSigner { /* private fields */ }

Holds the shared secret + signs / verifies tokens. One signer per process; adopters rotate via the secrets service (§10.f) on the cadence they prefer.

Implementations

impl ContinuityTokenSigner

pub fn new(key: impl Into<Vec<u8>>) -> Self

Wrap an adopter-supplied secret. Accepts any byte length; 32 bytes of CSPRNG output is the recommended size (matches §10.e signer-key guidance).

pub fn sign(&self, token: &ContinuityToken) -> String

Produce the wire-encoded token. The wire format is base64url_no_pad(session_id || 0x1e || expiry_ms || 0x1e || hex_lower(HMAC-SHA256)), computed by the C23 kernel in axon-csys.

pub fn verify(&self, raw: &str) -> Result<ContinuityToken, ContinuityTokenError>

Verify + parse. Returns the bound ContinuityToken on success, typed error otherwise.

Trait Implementations

impl Clone for ContinuityTokenSigner

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

Performs copy-assignment from source.

impl Debug for ContinuityTokenSigner

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

Formats the value using the given formatter.
