GI.Gio.Objects.SimplePermission
Contents
Description
SimplePermission is a trivial implementation of Permission that
represents a permission that is either always or never allowed. The
value is given at construction and doesn't change.
Calling request or release will result in errors.
Synopsis
- newtype SimplePermission = SimplePermission (ManagedPtr SimplePermission)
- class GObject o => IsSimplePermission o
- toSimplePermission :: (MonadIO m, IsSimplePermission o) => o -> m SimplePermission
- noSimplePermission :: Maybe SimplePermission
- simplePermissionNew :: (HasCallStack, MonadIO m) => Bool -> m SimplePermission
Exported types

toSimplePermission :: (MonadIO m, IsSimplePermission o) => o -> m SimplePermission Source #
Cast to SimplePermission, for types for which this is known to be safe. For general casts, use castTo.
noSimplePermission :: Maybe SimplePermission Source #
A convenience alias for Nothing :: Maybe SimplePermission.
