Struct Authority 

pub struct Authority { /* private fields */ }

A portable authority value: exactly the mesh Caveats lattice, given a stable content identity for the first time. Introducing an identity, not a new authority model — Newt has no Grant type today; authority is a bare Caveats, so AuthorityId is the first stable name a delegated authority ever gets.

Implementations

impl Authority

pub fn new(caveats: Caveats) -> Self

Wrap a Caveats as a content-addressable authority value.

pub fn caveats(&self) -> &Caveats

The authority lattice value.

pub fn id(&self) -> Result<AuthorityId, ContentError>

This authority’s typed content id (L1).

Errors

Propagates a dag-cbor encoding error (e.g. a non-finite float — impossible for Caveats, which has no floats).

Trait Implementations

impl Clone for Authority

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl ContentAddressable for Authority

fn canonical_form(&self) -> Result<Vec<u8>, ContentError>

Produce the deterministic byte representation of this value.

fn content_id(&self) -> Result<ContentId, ContentError>

Compute this value’s ContentId.

fn verify(&self, expected: &ContentId) -> Result<bool, ContentError>

Check whether this value’s content id matches an expected id.

fn ensure_content_id(&self, expected: &ContentId) -> Result<(), ContentError>

Verify, returning an error on mismatch instead of Ok(false).

fn from_canonical_form(bytes: &[u8]) -> Result<Self, ContentError>

where Self: Sized + DeserializeOwned,

Checked ingress: decode a value from its canonical form, proving the bytes reproduce it — a checked partial inverse of canonical_form.

impl Debug for Authority

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Authority

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Authority

impl PartialEq for Authority

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Authority

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
