Bilingual Errors

All BaseID errors implement BilingualError:

use baseid_core::error::BilingualError;
use baseid_core::language::Language;

let error = some_operation().unwrap_err();
println!("EN: {}", error.message(Language::En));
println!("FR: {}", error.message(Language::Fr));

This is a core requirement for Canadian government deployments where both official languages must be supported.

Lifecycle Traits

The credential lifecycle is modeled with three traits:

pub trait CredentialIssuer {
    fn issue(&self, request: &IssuanceRequest) -> Result<IssuedCredential>;
}

pub trait CredentialVerifier {
    fn verify(&self, credential: &[u8]) -> Result<VerifiedClaims>;
}

pub trait CredentialPresenter {
    fn present(&self, request: &PresentationRequest) -> Result<Presentation>;
}

Each credential format crate implements these traits.

ClaimSet

A namespace-keyed data structure for credential claims:

use baseid_core::claims::ClaimSet;

let mut claims = ClaimSet::new();
claims.insert("org.iso.18013.5.1", "family_name", "Smith".into());
claims.insert("org.iso.18013.5.1", "given_name", "Alice".into());
