Struct SoftBinding 

pub struct SoftBinding {
    pub alg: String,
    pub blocks: Vec<Block>,
    pub name: Option<String>,
    pub pad: Vec<u8>,
}

A soft-binding-map: one or more soft bindings over the asset’s content.

Field layout and names match the C2PA CDDL and the c2pa-rs reader. pad is always emitted (an empty byte string) as the reference writer does.

Fields

alg: String

The registered soft-binding algorithm identifier.

blocks: Vec<Block>

One block per scoped soft-binding value.

name: Option<String>

A human-readable description of what this binding covers.

pad: Vec<u8>

Zero-filled padding; kept empty. Present to match the reference writer.

Implementations

impl SoftBinding

pub fn whole(alg: &str, value_hex: String) -> Self

A whole-asset soft binding: one block with an empty scope.

pub fn push_window(&mut self, start: usize, len: usize, value_hex: String)

Push a block scoped to the character range [start, start+len) of the normalized stream. Used to record the surface fingerprint’s windows.

pub fn to_cbor(&self) -> Result<Vec<u8>, Error>

Serialize to deterministic CBOR (the assertion payload to be signed).

pub fn from_cbor(bytes: &[u8]) -> Result<Self, Error>

Parse a soft-binding assertion back from CBOR (for verifiers and tests).
