Struct SignaturePresence 

pub struct SignaturePresence {
    pub algorithm: Option<String>,
    pub key_id: Option<String>,
    pub signer_count: usize,
}

Structural record that a JSF (JSON Signature Format) signature object was present, and what it names.

PRESENCE ONLY: the signature bytes are neither retained nor verified. Consumers must treat this as EvidenceLevel::SignaturePresent at most.

Fields

algorithm: Option<String>

Signature algorithm named by the JSF object (e.g. “ES256”), when the object (or its first signer) declares one.

key_id: Option<String>

keyId named by the JSF object (or its first signer), when present.

signer_count: usize

Number of signers: 1 for the single-signature JSF form, the array length for the signers/chain multi-signature forms.

Implementations

impl SignaturePresence

pub fn from_jsf(value: &Value) -> Option<Self>

Structurally inspect a raw JSF signature value.

Handles the three JSF top-level forms (single signature, signers array, chain array). Returns None for non-object values. No cryptographic verification is performed.

Trait Implementations

impl Clone for SignaturePresence

fn clone(&self) -> SignaturePresence

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SignaturePresence

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

Formats the value using the given formatter.

impl Default for SignaturePresence

fn default() -> SignaturePresence

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for SignaturePresence

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for SignaturePresence

impl PartialEq for SignaturePresence

fn eq(&self, other: &SignaturePresence) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Serialize for SignaturePresence

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
