Expand description

A DID Document Verification Method.

Specification

Implementations§

Source§

impl VerificationMethod

Source

pub fn builder(properties: BTreeMap<String, Value>) -> MethodBuilder

Creates a MethodBuilder to configure a new Method.

This is the same as MethodBuilder::new().

Source

pub fn from_builder(builder: MethodBuilder) -> Result<VerificationMethod, Error>

Returns a new Method based on the MethodBuilder configuration.

Source

pub fn id(&self) -> &DIDUrl

Returns a reference to the VerificationMethod id.

Source

pub fn set_id(&mut self, id: DIDUrl) -> Result<(), Error>

Sets the VerificationMethod id.

§Errors

Error::MissingIdFragment if there is no fragment on the DIDUrl.

Source

pub fn controller(&self) -> &CoreDID

Returns a reference to the VerificationMethod controller.

Source

pub fn controller_mut(&mut self) -> &mut CoreDID

Returns a mutable reference to the VerificationMethod controller.

Source

pub fn type_(&self) -> &MethodType

Returns a reference to the VerificationMethod type.

Source

pub fn type_mut(&mut self) -> &mut MethodType

Returns a mutable reference to the VerificationMethod type.

Source

pub fn data(&self) -> &MethodData

Returns a reference to the VerificationMethod data.

Source

pub fn data_mut(&mut self) -> &mut MethodData

Returns a mutable reference to the VerificationMethod data.

Source

pub fn properties(&self) -> &BTreeMap<String, Value>

Returns a reference to the custom VerificationMethod properties.

Source

pub fn properties_mut(&mut self) -> &mut BTreeMap<String, Value>

Returns a mutable reference to the custom VerificationMethod properties.

Source

pub fn into_method_ref(self) -> MethodRef

Creates a new MethodRef from self.

Source

pub fn map<F>(self, f: F) -> VerificationMethod
where F: FnMut(CoreDID) -> CoreDID,

Maps the VerificationMethod by applying a function f to the CoreDID components of id and controller. Useful when working with DID methods where the identifier is not known before publishing.

Source

pub fn try_map<F, E>(self, f: F) -> Result<VerificationMethod, E>
where F: FnMut(CoreDID) -> Result<CoreDID, E>,

Fallible version of VerificationMethod::map.

Source§

impl VerificationMethod

Source

pub fn new_from_jwk<D>( did: D, key: Jwk, fragment: Option<&str>, ) -> Result<VerificationMethod, Error>
where D: DID,

Creates a new VerificationMethod from the given did and Jwk. If fragment is not given the kid value of the given key will be used, if present, otherwise an error is returned.

§Recommendations

The following recommendations are essentially taken from the publicKeyJwk description from the DID specification:

  • It is recommended that verification methods that use Jwks to represent their public keys use the value of kid as their fragment identifier. This is done automatically if None is passed in as the fragment.
  • It is recommended that Jwk kid values are set to the public key fingerprint. See Jwk::thumbprint_sha256_b64.
