Struct CapabilitySet 

pub struct CapabilitySet(/* private fields */);

A deterministically ordered open capability set.

Implementations

impl CapabilitySet

pub const fn new() -> Self

Construct an empty set.

pub fn insert(&mut self, capability: CapabilityId) -> bool

Insert one capability.

pub fn contains(&self, capability: &CapabilityId) -> bool

Return whether one capability is present.

pub fn len(&self) -> usize

Return the number of capabilities.

pub fn is_empty(&self) -> bool

Return whether the set is empty.

pub fn iter(&self) -> impl ExactSizeIterator<Item = &CapabilityId>

Iterate in deterministic lexical order.

pub fn missing_from(&self, available: &Self) -> Self

Return capabilities in this required set that are absent from available.

pub fn ensure_supported_by(&self, available: &Self) -> Result<(), Diagnostic>

Reject missing required capabilities before provider I/O.
