# safetypes
Rust like result and option implementation for golang
just a reminder, option type is ready for (un)marshalling, mongodb and rethinkdb so feel free to use it with ^^
## Examples
```go
import safe "github.com/eminarican/safetypes"
```
### Option
```go
func checkUnwrap(opt safe.Option[int]) {
if opt.IsSome() {
println(opt.Unwrap())
} else {
panic("poor option :(")
}
}
```
```go
func checkUnwrapOr(opt safe.Option[int]) {
println(opt.UnwrapOr(10))
}
```
```go
func retrunOption(some bool) (opt safe.Option[int]) {
if some {
return opt.Some(7)
}
return opt.None()
}
```
```go
type Test struct {
Field safe.Option[int]
}
func jsonMarshal(t Test) {
res := safe.AsResult(json.Marshal(s))
if res.IsOk() {
// if some: "Test{Field: 7}"
// if none: "Test{Field: {}}"
println(res.Unwrap())
} else {
panic(res.Error())
}
}
```
### Result
```go
func checkUnwrap(res safe.Result[int]) {
if res.IsOk() {
println(res.Unwrap())
} else {
panic(res.Error())
}
}
```
```go
func retrunResult(some bool) (res safe.Result[int]) {
if some {
return res.Ok(7)
}
return res.Err("some fancy error msg")
}
```
### Note
Error and None methods usable as structless but it doesn't infere types so instead of using `safetypes.None[T]()` and `safetypes.Err[T]("")` you could use them as how in examples above
