Function transform 

pub fn transform<S>(
    template: &Template<'_, '_>,
    ctx: S,
    output: &OutputFormat,
) -> Result<Output, OperationOutcomeError>
where
    S: Serialize,

Renders a template into the requested output format.

The template is rendered using the provided serializable context and the resulting text is validated or parsed according to output.

• OutputFormat::FHIR parses the rendered output as a FHIR resource.
• OutputFormat::JSON parses the rendered output as arbitrary JSON.
• OutputFormat::HL7V2 validates that the rendered output is a valid HL7 v2 message.

Errors

Returns an [OperationOutcomeError] if:

• template rendering fails,
• the rendered output cannot be parsed as the requested format, or
• HL7 v2 validation fails.
