Struct async_ffi::LocalBorrowingFfiFuture[−][src]

#[repr(C)]
pub struct LocalBorrowingFfiFuture<'a, T> { /* fields omitted */ }
Expand description

The FFI compatible future type without Send bound.

Non-Send Futures can only be converted into LocalFfiFuture. It is not able to be spawnd in a multi-threaded runtime, but is useful for thread-local futures, single-threaded runtimes, or single-threaded targets like wasm.

See module level documentation for more details.

Implementations

impl<'a, T> LocalBorrowingFfiFuture<'a, T>[src]

pub fn new<F: Future<Output = T> + 'a>(fut: F) -> Self[src]

Convert a Rust Future into a FFI-compatible LocalFfiFuture.

Usually into_local_ffi is preferred and is identical to this method.
