Trait MaybeSend 

pub trait MaybeSend: Send { }

Available on non-WebAssembly only.

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.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
