Struct Attestation 

#[non_exhaustive]
pub struct Attestation {
    pub content: Hash,
    pub issuer: String,
    pub kind: AttestationKind,
    pub value: String,
    pub sequence: u64,
    pub issued_at: u64,
    pub signature: Option<String>,
}

A signed license, provenance, or derivative attestation.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

content: Hash

issuer: String

kind: AttestationKind

value: String

sequence: u64

issued_at: u64

signature: Option<String>

Implementations

impl Attestation

pub fn new( content: Hash, kind: AttestationKind, value: impl Into<String>, sequence: u64, signing_key: &SigningKey, ) -> Result<Self>

Create and sign an attestation.

Errors

Returns an error if attestation fields are invalid.

pub fn sign(&mut self, signing_key: &SigningKey) -> Result<()>

Sign the attestation with the declared issuer.

Errors

Returns an error if the signing key does not match the issuer.

pub fn verify_signature(&self) -> Result<()>

Verify the attestation signature.

Errors

Returns an error if the attestation or signature is invalid.

pub fn validate(&self) -> Result<()>

Validate attestation fields.

Errors

Returns an error if a field is invalid.
