func GoFunction(int) (int, float64) struct { int i; float64 f; } CFunction(int, void*) Go interface, channel, and map types have no corresponding C type (interface is a two-element struct and channel and map are pointers to structs in C, but the structs are deliberately undocumented...
于是,golang对于带/不带 Type Constraints 的 interface 的使用场景也是有区别的,带有 Type Constraints 的 interface只能用作泛型的类型限制,保证类型参数的值必须在特定范围内 带有Type Constraint 的 interface 只能用作泛型中的类型限制。从这种意义上看,interface with Type Constraint 可以认为是新的类型 // You ...
// internal/task-runner/runner.go type Runner interface { Run(ctx context.Context, doneCh chan<- bool) } Note that we’re using a done channel (doneCh). This is required for us to run our task asynchronously — and it also notifies us once this task is complete. You can find yo...

Arrays are represented by []interface{}. Primitive types are string, bool, float64, or int64. The method UnstructuredContent() provides access to this data structure inside of an unstructured object (we can also just access Unstructured.Object). There are helpers in the same package to make ...
