is a mechanism for tracking the progress of an asynchronous
operation.
Implementations

pub fn from_success() -> TokenⓘNotable traits for Tokenimpl Future for Token type Output = Result<ServerResponse>;
Creates a new Token signaled with a “success” return code.
sourcepub fn wait(self) -> Result<ServerResponse>
pub fn wait(self) -> Result<ServerResponse>
Blocks the caller until the asynchronous operation completes.

pub fn try_wait(&mut self) -> Option<Result<ServerResponse>>
Non-blocking check to see if the token is complete.
Returns None
if the operation is still in progress, otherwise
returns the result of the operation which can be an error or,
on success, the response from the server.
sourcepub fn wait_for(self, dur: Duration) -> Result<ServerResponse>
pub fn wait_for(self, dur: Duration) -> Result<ServerResponse>
