# intcast

`intcast` identifies integer type casts that can potentially cause overflow.

```go

func f(i int) uint {

  return uint(i) // unsafe cast

}

```

`intcast` also handles casts on defined types.

```go

type MyInt int

func f(i MyInt) uint {

  return uint(i) // unsafe cast

}

```

`intcast` ignores lines with ignore comments.

```go

func f(i int) uint {

  //lint:ignore intcast reason

  return uint(i)

}

```

## How to use

```sh

go install github.com/qawatake/intcast/cmd/intcast@latest

intcast ./...

```
