Struct CapabilitySet 

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

A set of capabilities held by a plugin instance.

Membership tests are O(1) on average.

Examples

use martensite_plugin::{Capability, CapabilitySet};

let mut caps = CapabilitySet::empty();
caps.grant(Capability::Network);
assert!(caps.contains(&Capability::Network));
caps.revoke(&Capability::Network);
assert!(!caps.contains(&Capability::Network));

Implementations

impl CapabilitySet

pub fn empty() -> Self

Creates an empty capability set.

pub fn builder() -> PluginBuilder

Returns a builder for constructing a capability set fluently.

pub fn len(&self) -> usize

Returns the number of distinct capabilities in the set.

pub fn is_empty(&self) -> bool

Returns true if no capabilities have been granted.

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

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

Revokes a capability, returning true if it was present.

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

Returns true if the capability is currently granted.
