# ineffective-value-receiver-assignment

**Default severity:** `warning`

A method with a value receiver modifies only its local receiver copy. When an
assigned field is never read afterward, the write has no observable effect and
often indicates that the method should use a pointer receiver.

The check follows field reads through the method's control-flow graph. It
does not report a local mutation that is subsequently read to compute a result.

## Bad

```go
func (item Item) Rename(name string) { item.Name = name }
```

## Good

```go
func (item *Item) Rename(name string) { item.Name = name }
```
