Struct noosphere_core::data::LinkRecord

#[repr(transparent)]
pub struct LinkRecord(_);

A LinkRecord is a wrapper around a decoded Jwt (Ucan), representing a link address as a Cid to a sphere.

Implementations

impl LinkRecord

pub async fn validate<S: UcanJwtStore>(&self, store: &S) -> Result<()>

Validates the Ucan token as a LinkRecord, ensuring that the sphere’s owner authorized the publishing of a new content address. Notably does not check the publishing timeframe permissions, as an expired token can be considered valid. Returns an Err if validation fails.

pub fn has_publishable_timeframe(&self) -> bool

Returns true if the Ucan token is currently publishable within the bounds of its expiry/not before time.

pub fn sphere_identity(&self) -> &str

The DID key of the sphere that this record maps.

pub fn get_link(&self) -> Option<Link<MemoIpld>>

The sphere revision address (Link) that the sphere’s identity maps to.

pub async fn collect_proofs<S>(&self, store: &S) -> Result<Vec<Ucan>>where S: UcanJwtStore,

Walk the underlying Ucan and collect all of the supporting proofs that verify the link publisher’s authority to publish the link

Methods from Deref<Target = Ucan>

pub async fn validate<'a>( &self, now_time: Option<u64>, did_parser: &mut DidParser ) -> impl Future<Output = Result<(), Error>>

Validate the UCAN’s signature and timestamps

pub async fn check_signature<'a>( &self, did_parser: &mut DidParser ) -> impl Future<Output = Result<(), Error>>

Validate that the signed data was signed by the stated issuer

pub fn encode(&self) -> Result<String, Error>

Produce a base64-encoded serialization of the UCAN suitable for transferring in a header field

pub fn is_expired(&self, now_time: Option<u64>) -> bool

Returns true if the UCAN has past its expiration date

pub fn signed_data(&self) -> &[u8]

Raw bytes of signed data for this UCAN

pub fn signature(&self) -> &[u8]

pub fn is_too_early(&self) -> bool

Returns true if the not-before (“nbf”) time is still in the future

pub fn lifetime_begins_before(&self, other: &Ucan) -> bool

Returns true if this UCAN’s lifetime begins no later than the other Note that if a UCAN specifies an NBF but the other does not, the other has an unbounded start time and this function will return false.

pub fn lifetime_ends_after(&self, other: &Ucan) -> bool

Returns true if this UCAN expires no earlier than the other

pub fn lifetime_encompasses(&self, other: &Ucan) -> bool

Returns true if this UCAN’s lifetime fully encompasses the other

Trait Implementations

impl Clone for LinkRecord

fn clone(&self) -> LinkRecord

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LinkRecord

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

Formats the value using the given formatter.

impl Deref for LinkRecord

type Target = Ucan

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.

impl<'de> Deserialize<'de> for LinkRecord

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for LinkRecord

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

Formats the value using the given formatter.

impl From<&LinkRecord> for Ucan

fn from(value: &LinkRecord) -> Self

Converts to this type from the input type.

impl From<&Ucan> for LinkRecord

fn from(value: &Ucan) -> Self

Converts to this type from the input type.

impl From<LinkRecord> for Ucan

fn from(value: LinkRecord) -> Self

Converts to this type from the input type.

impl From<Ucan> for LinkRecord

fn from(value: Ucan) -> Self

Converts to this type from the input type.

impl FromStr for LinkRecord

type Err = Error

The associated error which can be returned from parsing.

fn from_str(value: &str) -> Result<Self, Self::Err>

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

impl PartialEq<LinkRecord> for LinkRecord

LinkRecords compare their Jwt representations for equality. If a record cannot be encoded as such, they will not be considered equal to any other record.

fn eq(&self, other: &Self) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for LinkRecord

fn serialize<S>(&self, serializer: S) -> Result<S::Ok, S::Error>where S: Serializer,

Serialize this value into the given Serde serializer.
