Enum Capability 

pub enum Capability {
    FsRead {
        root: PathRoot,
    },
    FsWrite {
        root: PathRoot,
    },
    Network {
        host: NetworkHost,
    },
    CrossComponentRead {
        target: ComponentId,
    },
}

One kind paired with its only valid scope type.

Variants

FsRead

Filesystem read authority rooted at root.

Fields

root: PathRoot

Absolute lexical root, or path being consumed during a check.

FsWrite

Filesystem write authority rooted at root.

Fields

root: PathRoot

Absolute lexical root, or path being consumed during a check.

Network

Network authority for exactly host.

Fields

host: NetworkHost

Exact host; no glob or pattern syntax is recognized.

CrossComponentRead

Read authority for exactly one foreign component.

Fields

target: ComponentId

Component whose ephemeral read-only view may be resolved.

Implementations

impl Capability

pub const fn kind(&self) -> CapabilityKind

Returns the closed kind represented by this scoped capability.

pub fn scope(&self) -> CapabilityScope

Returns a typed copy of this capability’s scope.

pub fn validate(&self) -> Result<(), ScopeValidationError>

Validates that this scope can be safely matched by the v1 exact rules.

Errors

Returns why a path root or exact host is malformed.

pub fn covers(&self, consumed: &Self) -> bool

Reports whether this declaration/grant covers one consuming act.

Filesystem roots use lexical path containment. Network and component scopes use exact equality; there is no glob or pattern interpretation.

Trait Implementations

impl Clone for Capability

fn clone(&self) -> Capability

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Capability
