DID method identifiers per W3C DID Core 1.0

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

Implementations

impl DIDMethod

pub fn resolve(&self, did: &DID) -> Result<Document, DIDError>

Resolve this DID method to a DID Document

Works for locally-resolvable methods (did:key, did:peer). For network methods, returns an error indicating external resolution is needed.

impl DIDMethod

pub fn name(&self) -> &str

Returns the method name (“key”, “peer”, “web”, etc.)

pub fn identifier(&self) -> &str

Returns the raw method-specific identifier

Trait Implementations

impl Clone for DIDMethod

fn clone(&self) -> DIDMethod

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DIDMethod

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for DIDMethod

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for DIDMethod

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

Formats the value using the given formatter.

impl PartialEq for DIDMethod

fn eq(&self, other: &DIDMethod) -> 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 DIDMethod

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 DIDMethod

impl StructuralPartialEq for DIDMethod
