Type Alias FizzyExternalFn 

pub type FizzyExternalFn = Option<unsafe extern "C" fn(host_ctx: *mut c_void, instance: *mut FizzyInstance, args: *const FizzyValue, ctx: *mut FizzyExecutionContext) -> FizzyExecutionResult>;

Pointer to external function.

@param host_ctx Opaque pointer to host context. @param instance Pointer to module instance. @param args Pointer to the argument array. Can be NULL iff function has no inputs. @param ctx Opaque pointer to execution context. If NULL new execution context will be allocated. @return Result of execution.

@note External functions implemented in C++ must be non-throwing, i.e. the effect of any exception escaping the function is std::terminate being called.
