Struct CapabilitySet 

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

An unordered set of capability strings held by a token.

Access control is pure set membership with a single special case: the WILDCARD string satisfies any required capability.

Implementations

impl CapabilitySet

pub fn new() -> Self

Create an empty capability set (holds no capabilities).

pub fn wildcard() -> Self

Create a wildcard set — satisfies every capability check.

This is the set held by the full-control preset and the legacy-key mapping target (spec §4).

pub fn satisfies(&self, required: &str) -> bool

Whether this set satisfies required — either it holds the wildcard, or it directly contains the required capability string.

This is the frozen access-decision primitive (spec §2.1).

pub fn is_wildcard(&self) -> bool

Whether this set holds the wildcard capability.

pub fn insert(&mut self, capability: impl Into<String>)

Insert a capability string into the set.

pub fn len(&self) -> usize

Number of capability strings in the set.

pub fn is_empty(&self) -> bool

Whether the set holds no capabilities.

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

Iterate over the capability strings.
