[−][src]Struct tokio_lock::Lock
This structure "locks" an object to be accessed from a single Tokio task.
Methods
impl<T, E> Lock<T, E> where
E: StdError + From<Error> + Send + 'static,
[src]
E: StdError + From<Error> + Send + 'static,
pub fn new() -> Self
[src]
Create new instance of a Lock
.
pub fn manage(
&mut self,
value: T
) -> impl Future<Item = (), Error = Error>
[src]
&mut self,
value: T
) -> impl Future<Item = (), Error = Error>
Consume value
and return a Future
for managing it.
pub fn get<CB, F, I>(
&mut self,
cb: CB
) -> impl Future<Item = I, Error = E> where
CB: FnMut(&T) -> F + Send + 'static,
F: Future<Item = I, Error = E> + Send + 'static,
I: Send + 'static,
[src]
&mut self,
cb: CB
) -> impl Future<Item = I, Error = E> where
CB: FnMut(&T) -> F + Send + 'static,
F: Future<Item = I, Error = E> + Send + 'static,
I: Send + 'static,
Get the managed object and invoke cb
with a reference to it.
pub fn get_mut<I, CB, F>(
&mut self,
cb: CB
) -> impl Future<Item = I, Error = E> where
CB: FnMut(&mut T) -> F + Send + 'static,
F: Future<Item = I, Error = E> + Send + 'static,
I: Send + 'static,
[src]
&mut self,
cb: CB
) -> impl Future<Item = I, Error = E> where
CB: FnMut(&mut T) -> F + Send + 'static,
F: Future<Item = I, Error = E> + Send + 'static,
I: Send + 'static,
Get the managed object and invoke cb
with a mutable reference to it.
pub fn stop(&mut self)
[src]
Stop managing the object.
