Struct LivePermissions 

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

A participant’s permissions as they stand now, following every change the host makes while the app runs: a role changed by the record’s owner, a grant revoked, a capability granted. Read-only: only the host changes them.

A PermissionContext is a snapshot; code that decides once at launch what a participant may do goes stale the moment their role changes. Hold one of these instead and ask again when it matters (every frame is cheap).

Implementations

impl LivePermissions

pub fn fixed(context: PermissionContext) -> LivePermissions

Permissions that never change: a preview of a past version, a capture, a test fixture.

pub fn check(&self, scope: &PermissionScope) -> bool

May the participant do this, as of now?

pub fn answer(&self, node: &TreePath, kind: ActionKind) -> Answer

The answer for an action of kind at node below the workspace, as of now.

pub fn workspace_has_others(&self) -> bool

Whether anyone besides the participant belongs to the workspace, its owner or a member, here now or not: what the workspace holds is shared with them.

pub fn current(&self) -> PermissionContext

The permissions in force now.
