Struct noosphere_core::api::headers::Ucan

pub struct Ucan(/* private fields */);

A typed header for the ucan header, a tuple of Cid and Jwt, adhering to the UCAN as Bearer Token specification.

TODO(#708): Note that in the 0.3.0 spec, a single ucans header is used. This implementation is based on an earlier version with multiple ucan headers.

The values are not validated during parsing beyond legitimate looking Cids and Jwts here. Use Ucan::as_proof_chain to validate and construct a ProofChain.

Implementations

impl Ucan

pub async fn as_proof_chain( &self, bearer: &Bearer, db: impl UcanJwtStore ) -> Result<ProofChain>

Construct a ProofChain from the collected ucan header values, validating the cryptographic integrity and time bounds of the UCANs. Capabilities can then be assessed using the ProofChain.

Trait Implementations

impl From<Ucan> for Vec<(Cid, Jwt)>

fn from(value: Ucan) -> Self

Converts to this type from the input type.

impl Header for Ucan

fn name() -> &'static HeaderName

The name of this header.

fn decode<'i, I>(values: &mut I) -> Result<Self, Error>where I: Iterator<Item = &'i HeaderValue>,

Decode this type from an iterator of HeaderValues.

fn encode<E>(&self, values: &mut E)where E: Extend<HeaderValue>,

Encode this type to a HeaderMap.
