# [−][src]Function rayon_core::join_context

    pub fn join_context<A, B, RA, RB>(oper_a: A, oper_b: B) -> (RA, RB) where
        A: FnOnce(FnContext) -> RA + Send,
        B: FnOnce(FnContext) -> RB + Send,
        RA: Send,
        RB: Send,

Identical to `join`, except that the closures have a parameter that provides context for the way the closure has been called, especially indicating whether they're executing on a different thread than where `join_context` was called. This will occur if the second job is stolen by a different thread, or if `join_context` was called from outside the thread pool to begin with.

## 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`)
