Struct Did 

pub struct Did(pub String);

A Decentralized Identifier (DID) for an agent.

DIDs follow the W3C DID Core specification. For CELLSTATE agents, we use the did:web method which resolves via HTTPS.

Format: did:web:{domain}:agents:{agent-uuid}

Tuple Fields

0: String

Implementations

impl Did

pub fn web(domain: &str, agent_id: Uuid) -> Self

Create a did:web identifier for an agent.

Arguments

• domain - The domain hosting the DID document (e.g., “cellstate.batterypack.dev”)
• agent_id - The agent’s UUID

Examples

let id = Uuid::nil();
let did = Did::web("cellstate.batterypack.dev", id);
assert_eq!(did.0, "did:web:cellstate.batterypack.dev:agents:00000000-0000-0000-0000-000000000000");

pub fn parse(s: &str) -> Option<Self>

Parse a DID string, returning Some(Did) if it begins with did:.

pub fn agent_id(&self) -> Option<Uuid>

Extract the agent UUID from a did:web identifier.

Returns None if the DID is not a did:web with the expected :agents:{uuid} suffix.

pub fn method(&self) -> &str

Get the DID method (e.g., “web”, “key”, “pkh”).

Returns the method portion of the DID string (did:{method}:...).

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

Formats the value using the given formatter.

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

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Did

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

Formats the value using the given formatter.

impl Hash for Did

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

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::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
