Struct ServiceCapabilities 

pub struct ServiceCapabilities {
    pub tsp: Option<String>,
    pub didcomm: Option<String>,
    pub https: Option<String>,
}

The transports a registry advertises, parsed from its DID document by service type.

Each field holds the endpoint to route to for that protocol:

• tsp / didcomm — the registry’s mediator DID, not a transport URL. Both use mediator indirection; the URL lives in the mediator’s own DID document, so a second resolution hop is required.
• https — the registry’s REST base URL, used directly.

Fields

tsp: Option<String>

Mediator DID advertised for TSP, if any.

didcomm: Option<String>

Mediator DID advertised for DIDComm, if any.

https: Option<String>

REST base URL advertised, if any.

Implementations

impl ServiceCapabilities

pub fn from_document(doc: &Value) -> Self

Parse the service array of a resolved DID document.

Unknown service types are ignored, entries missing a usable endpoint are skipped, and the first entry of each type wins — a document advertising two DIDComm services is not an error, it just has one preferred.

pub fn endpoint(&self, kind: TransportKind) -> Option<&str>

The endpoint advertised for kind, if any.

pub fn advertised(&self) -> Vec<TransportKind>

Every transport advertised, in preference order.

pub fn select( &self, ours: &[TransportKind], ) -> Result<TransportChoice, TrqlError>

Choose the transport to use: the highest-preference one present in both ours and this capability set.

Returns TrqlError::NoMatchingTransport carrying both sides’ sets when the intersection is empty, so an operator can see what each side offers rather than guessing why a query failed.
