Struct InTotoStatement 

pub struct InTotoStatement {
    pub type_uri: String,
    pub subject: Vec<Subject>,
    pub predicate_type: String,
    pub predicate: SlsaProvenancePredicate,
}

in-toto v1 Statement wrapping a SLSA provenance predicate.

Fields

type_uri: String

Always IN_TOTO_STATEMENT_TYPE.

subject: Vec<Subject>

The artifacts this statement attests to.

predicate_type: String

Predicate type URI.

predicate: SlsaProvenancePredicate

The predicate body.

Implementations

impl InTotoStatement

pub fn to_json(&self) -> Result<String>

Serialise to JSON.

Errors

Propagates serde_json errors.

pub fn canonical_bytes(&self) -> Result<Vec<u8>>

Canonical bytes used for DSSE PAE.

Errors

Propagates serde_json errors.

pub fn to_jcs_bytes(&self) -> Result<Vec<u8>>

RFC 8785 (JCS) canonical bytes — use when cross-implementation byte stability matters (Phase B of RFC-0031). Opt-in; Self::canonical_bytes remains the signature-stable form for historical DSSE envelopes.

Errors

Propagates serialization errors from crate::jcs.

pub fn from_json(s: &str) -> Result<Self>

Parse from JSON.

Errors

Returns Err for malformed JSON or schema mismatches.

Trait Implementations

impl Clone for InTotoStatement

fn clone(&self) -> InTotoStatement

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for InTotoStatement

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for InTotoStatement

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for InTotoStatement

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for InTotoStatement

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for InTotoStatement
