Struct JwtEncoder 

pub struct JwtEncoder { /* private fields */ }

JWT token encoder. Signs tokens using a TokenSigner.

Register in Registry for handler access via Service<JwtEncoder>. Cloning is cheap — state is stored behind Arc.

Implementations

impl JwtEncoder

pub fn from_config(config: &JwtConfig) -> Self

Creates a JwtEncoder from YAML configuration.

Uses HmacSigner (HS256) with the configured secret. The validation config (leeway, issuer, audience) is stored so a matching JwtDecoder can be created via JwtDecoder::from(&encoder).

pub fn encode<T: Serialize>(&self, claims: &Claims<T>) -> Result<String>

Encodes claims into a signed JWT token string.

If claims.exp is None and default_expiry is configured, exp is automatically set to now + default_expiry before signing. An explicitly set exp is never overwritten.

Errors

Returns Error::internal with JwtError::SerializationFailed if the claims cannot be serialized to JSON, or JwtError::SigningFailed if the HMAC signing operation fails.

Trait Implementations

impl Clone for JwtEncoder

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl From<&JwtEncoder> for JwtDecoder

Creates a JwtDecoder that shares the signing key and validation config of an existing JwtEncoder. Useful when encoder and decoder are wired from the same JwtConfig value.

fn from(encoder: &JwtEncoder) -> Self

Converts to this type from the input type.
