Fields

created: Option<Timestamp>

When the proof was generated.

expires: Option<Timestamp>

When the proof expires.

challenge: Option<String>

Challenge from a proof requester to mitigate replay attacks.

domain: Option<String>

Domain for which a proof is valid to mitigate replay attacks.

purpose: Option<ProofPurpose>

Purpose for which the proof was generated.

Implementations

impl Proof

pub fn new(type_: impl Into<String>, method: impl Into<String>) -> Proof

Creates a new Proof instance with the given type_ and method, with the rest of its properties left unset.

pub fn new_with_options(
    type_: impl Into<String>,
    method: impl Into<String>,
    options: ProofOptions
) -> Proof

Creates a new Proof instance with the given properties.

pub fn type_(&self) -> &str

Returns the type property of the proof.

pub fn verification_method(&self) -> &str

Returns the identifier of the DID method used to create this proof.

pub const fn value(&self) -> &ProofValue

Returns a reference to the proof value.

pub fn value_mut(&mut self) -> &mut ProofValue

Returns a mutable reference to the proof value.

pub fn set_value(&mut self, value: ProofValue)

Sets the ProofValue of the object.

pub fn clear_value(&mut self)

Clears the current proof value - all other properties are unchanged.

pub fn hide_value(&self)

Flag the proof value so it is ignored during serialization

pub fn show_value(&self)

Restore the proof value state so serialization behaves normally

Trait Implementations

impl Clone for Proof

fn clone(&self) -> Proof
