Struct SignatureBuilder 

pub struct SignatureBuilder { /* private fields */ }

Builder for a complete XMLDSig <Signature> template.

Implementations

impl SignatureBuilder

pub fn new(c14n_method: C14nAlgorithm, sign_method: SignatureAlgorithm) -> Self

Create a signature template using the required algorithms.

pub fn ns_prefix(self, prefix: impl Into<String>) -> Self

Use a namespace prefix such as ds; the default is an unprefixed namespace.

pub fn signature_id(self, id: impl Into<String>) -> Self

Set the optional Signature Id.

pub fn signature_context(self, context: SignatureContext) -> Self

Set the authenticated cryptographic context for a context-capable method. Nonempty contexts on other methods are rejected, never silently ignored.

pub fn add_reference(self, reference: ReferenceBuilder) -> Self

Append a reference, preserving insertion order.

pub fn key_info(self, include: bool) -> Self

Control whether an empty KeyInfo placeholder is emitted.

pub fn build_template(&self) -> Result<String, SignatureBuilderError>

Build a namespace-correct XMLDSig template with empty digest and signature values.

pub fn build_template_with_policy( &self, policy: &SigningPolicy, ) -> Result<String, SignatureBuilderError>

Build a template after enforcing the same immutable policy snapshot used by the signing operation that will consume it. This key-independent method validates generated digest widths; SignContext::sign_with_builder additionally validates the exact key-dependent SignatureValue width.

Trait Implementations

impl Clone for SignatureBuilder

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignatureBuilder

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

Formats the value using the given formatter.
