Struct CapabilitySet 

pub struct CapabilitySet { /* private fields */ }

Set of capabilities currently granted to a connection. Deterministically ordered (BTreeSet) so granted() returns a stable sequence — important for wire-level reproducibility and test assertions.

Implementations

impl CapabilitySet

pub fn empty() -> Self

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

pub fn granted(&self) -> Vec<String>

Sorted, deterministic view of the granted set.

pub fn intersect(&self, requested: &[String]) -> (Vec<String>, Vec<String>)

Intersect requested with the server’s allow-list. Returns (granted_subset, denied_subset), each deterministically ordered. Used during the Hello handshake to decide what to echo back.

pub fn union(&self, other: &Self) -> Self

Union two capability sets. Used by SP-capability-v2 dispatch to combine SP-12 string-allow-list results with UCAN-derived caps (spec §4.2: granted = granted_strings ∪ granted_ucan). Returns a new set; neither input is mutated.

Trait Implementations

impl Clone for CapabilitySet

fn clone(&self) -> CapabilitySet

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for CapabilitySet

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

Formats the value using the given formatter.

impl Default for CapabilitySet

fn default() -> CapabilitySet

Returns the “default value” for a type.

impl FromIterator<String> for CapabilitySet

fn from_iter<I: IntoIterator<Item = String>>(iter: I) -> Self

Creates a value from an iterator.
