Struct CapabilitySet 

pub struct CapabilitySet { /* private fields */ }

A set of granted capabilities, used as the capability state of a Cx.

Examples

let cap = CapabilityName::new("read-construct");
let granted = CapabilitySet::new().grant(cap.clone());
assert!(granted.contains(&cap));

Implementations

impl CapabilitySet

pub fn new() -> Self

Builds an empty capability set.

pub fn grant(self, capability: CapabilityName) -> Self

Returns the set with one more capability granted (builder style).

pub fn insert(&mut self, capability: CapabilityName)

Grants a capability in place.

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

Reports whether the capability is granted.

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

Iterates the granted capabilities in sorted order.

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 Eq for CapabilitySet

impl PartialEq for CapabilitySet

fn eq(&self, other: &CapabilitySet) -> 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.
