Struct Did 

pub struct Did {
    pub method: DidMethod,
    pub id: String,
}

W3C Decentralized Identifier (DID)

A DID is a globally unique identifier that enables verifiable, decentralized digital identity.

Fields

method: DidMethod

The DID method (lux, key, web)

id: String

The method-specific identifier

Implementations

impl Did

pub fn new(method: DidMethod, id: String) -> Did

Create a new DID with the specified method and ID

pub fn parse(s: &str) -> Result<Did, Error>

Parse a DID from a string in the format “did:method:id”

Example

let did = Did::parse("did:lux:z6MkhaXgBZDvotDkL5257faiztiGiC2QtKLGpbnnEGta2doK")?;
assert_eq!(did.method, DidMethod::Lux);

pub fn from_mldsa_key(public_key: &[u8]) -> Result<Did, Error>

Create a DID from an ML-DSA-65 public key

The resulting DID uses the did:key method with multibase-encoded multicodec-prefixed public key.

Example

let signer = PQSignature::generate()?;
let did = Did::from_mldsa_key(&signer.public_key_bytes())?;
println!("DID: {}", did); // did:key:z6Mk...

pub fn from_mldsa_key_lux(public_key: &[u8]) -> Result<Did, Error>

Create a Lux blockchain-anchored DID from an ML-DSA public key

pub fn from_web(domain: &str, path: Option<&str>) -> Result<Did, Error>

Create a web DID from a domain and optional path

Example

let did = Did::from_web("example.com", Some("users/alice"))?;
assert_eq!(did.to_string(), "did:web:example.com:users:alice");

pub fn uri(&self) -> String

Get the full DID URI string

pub fn document(&self) -> Result<DidDocument, Error>

Generate a W3C DID Document for this DID

The document includes verification methods and service endpoints.

Trait Implementations

impl Clone for Did

fn clone(&self) -> Did

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Did

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Did

fn deserialize<__D>( __deserializer: __D, ) -> Result<Did, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Did

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

Formats the value using the given formatter.

impl FromStr for Did

type Err = Error

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Did, Error>

Parses a string s to return a value of this type.

impl Hash for Did

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for Did

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

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Did
