Struct Grant 

pub struct Grant { /* private fields */ }

A grant: a reference to an Authority value plus the Derivation that justifies holding it.

The id-split fix: the grant references its authority by AuthorityId rather than inlining the Caveats, so the authority value and the grant are two distinct objects with two distinct CIDs. The same authority reached by two different derivations is two different grants (correct), and a grant’s identity is not silently a re-hash of the raw caveats.

Implementations

impl Grant

pub fn new(authority: AuthorityId, derivation: Derivation) -> Self

A grant over authority justified by derivation.

pub fn authority(&self) -> AuthorityId

The authority this grant confers, by content id.

pub fn derivation(&self) -> &Derivation

How this grant was derived.

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

This grant’s typed content id (L1).

Errors

Propagates a dag-cbor encoding error.

Trait Implementations

impl Clone for Grant

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 Grant

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 Grant

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Grant

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for Grant

impl PartialEq for Grant

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

Equality operator ==.

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

Inequality operator !=.

impl Serialize for Grant

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
