Struct AuthorityScope 

pub struct AuthorityScope { /* private fields */ }

A scope is a set of capabilities — the bounded authority a Principal::Delegate may exercise relative to its authorizing principal. ADR-0019 §Authority chain composition rule 1: a delegate’s scope MUST be a subset of the authorizing principal’s effective scope.

Backed by BTreeSet so the canonical URI form is deterministic (sorted) and round-trips byte-stably.

Implementations

impl AuthorityScope

pub fn empty() -> Self

Empty scope — useful for Operator/Platform/Federated principals (their “effective scope” for composition purposes is “all known capabilities”, represented by AuthorityScope::root).

pub fn root() -> Self

Scope containing every known capability. The effective scope a non-Delegate principal exposes to a downstream delegate per ADR-0019 §Authority chain composition rule 1.

pub fn from_capabilities<I: IntoIterator<Item = Capability>>(caps: I) -> Self

Build a scope from an explicit capability list.

pub fn contains(&self, cap: &Capability) -> bool

pub fn is_superset_of(&self, other: &AuthorityScope) -> bool

Returns true iff every capability in other is reachable from self — other ⊆ self. The composition rule predicate.

pub fn iter(&self) -> impl Iterator<Item = &Capability>

pub fn is_empty(&self) -> bool

pub fn len(&self) -> usize

Trait Implementations

impl Clone for AuthorityScope

fn clone(&self) -> AuthorityScope

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for AuthorityScope

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

Formats the value using the given formatter.

impl Default for AuthorityScope

fn default() -> AuthorityScope

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for AuthorityScope

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for AuthorityScope

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for AuthorityScope

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
