Struct arret_runtime::boxed::FunThunk

#[repr(C, align(16))]
pub struct FunThunk { /* fields omitted */ }

Boxed function value with optional captures

This is typically used in places where functions are used as values or stored in collections. For example, placing a function in a list will create a FunThunk. When taking an function as a parameter to an RFI function it’s typically better to use a typed callback::Callback.

Implementations
