Quick Start

[dependencies]
tpt-doc-fhir = "0.1"
tpt-doc-sign = "0.1"

use tpt_doc_fhir::prelude::*;
use tpt_doc_sign::prelude::*;

// Build a strictly typed FHIR Patient resource
let patient = Patient::builder()
    .id("nz-12345".into())
    .name(HumanName::new("Smith", "John"))
    .build()?;

// Serialize to compliant JSON
let json_bytes = patient.to_json()?;

// Sign for HIPC 2020 compliance
let signature = tpt_doc_sign::pades::sign(&json_bytes, &private_key)?;

Compliance Targets

• NZISM — New Zealand Information Security Manual
• HL7 FHIR R5 — Fast Healthcare Interoperability Resources
• HIPC 2020 — Health Information Privacy Code
