pub trait MaybeSend: Send { }
Expand description
MaybeSend is a marker to determine whether a type is Send
or not.
We use this trait to wrap the Send
requirement for wasm32 target.
§Safety
MaybeSend
is equivalent to Send
on non-wasm32 target.
And it’s empty trait on wasm32 target to indicate that a type is not Send
.
source§Available on non-WebAssembly only.
