Implementations§

Source§

impl TokenRegistry

Source

pub fn new() -> Self

Source

pub fn get_token<T: TokenInterface>( owner: Pin<&Tokenizable<T>>, ) -> Result<Handle, Status>

Returns a token for the owner, creating one if one doesn’t already exist. Tokens will be automatically removed when Tokenizable is dropped.

Source

pub fn get_owner( &self, token: Handle, ) -> Result<Option<Arc<dyn MutableDirectory>>, Status>

Returns the information provided by get_node_and_flags for the given token. Returns None if no such token exists (perhaps because the owner has been dropped).
