SPARQL-DID Handler

Fields

quins: &'a [NQuin]

did_cache: [Option<DidCacheEntry>; 32]

cache_count: u8

Implementations

impl<'a> SparqlDidHandler<'a>

pub fn new(quins: &'a [NQuin]) -> Self

pub fn resolve_did(&mut self, did: u64) -> Result<DidResolutionPointer, String>

Resolve a u64 DID pointer to ABI-layer endpoint/verification pointers (with caching).

endpoint_url and verification_method are derived via FNV-1a over the DID’s 60-bit identity bytes, salted with a method tag — not XOR with a magic number. They live in the same q_hash pointer space as the rest of the SPARQL engine. The human-readable URL and verification-method string for a DID are available via DIDResolver::resolve.

pub fn verify_signature( &self, _did: u64, signature: &[u8], data: &[u8], ) -> Result<DidVerificationResult, String>

Verify DID signature (zero-allocation using stack-allocated key frame)

pub fn check_permission( &self, did: u64, graph: u64, permission_type: u8, ) -> Result<DidPermissionResult, String>

Check DID permission for graph access

pub fn authenticate_did( &self, did: u64, auth_method: u8, _auth_payload: &[u8], ) -> Result<bool, String>

Authenticate with DID (strips heavy payloads at boundary)

pub fn sign_with_did(&self, did: u64, data: &[u8]) -> Result<Vec<u8>, String>

Sign data with DID (zero-allocation)

pub fn invalidate_cache(&mut self, did: u64)

Invalidate cache entry

Trait Implementations

impl<'a> Default for SparqlDidHandler<'a>

fn default() -> Self

Returns the “default value” for a type.
