# Function std::future::get_task_cx[−][src]

    pub fn get_task_cx<F, R>(f: F) -> R where
        F: FnOnce(&mut Context) -> R,

🔬 This is a nightly-only experimental API. (`gen_future` #50547)

Retrieves the thread-local task context used by async/await futures.

This function acquires exclusive access to the task context.

Panics if no task has been set or if the task context has already been retrived by a surrounding call to get_task_cx.

## Search Tricks

Prefix searches with a type followed by a colon (e.g. `fn:`) to restrict the search to a given type.

Accepted types are: `fn`, `mod`, `struct`, `enum`, `trait`, `type`, `macro`, and `const`.

Search functions by type signature (e.g. `vec -> usize` or `* -> vec`)

Search multiple things at once by splitting your query with comma (e.g. `str,u8` or `String,struct:Vec,test`)
