There are two ways to create errors —
|
||||
|
||||
With `erorr.Error`:
|
||||
|
||||
```
|
||||
const err error = erorr.Error("internal-error")
|
||||
```
|
||||
|
||||
**NOTICE THAT THAT ERROR IS A `const` RATHER THAN A `var`.**
|
||||
|
||||
**Errors creating using `erorr.Error` can be a Go `const`.**
|
||||
|
||||
And with `erorr.Errorf`:
|
||||
|
||||
```
|
||||
var err error = erorr.Errorf("bad value for id %q", id)
|
||||
```
|
||||
|
||||
**One thing to notice is that `erorr.Error` errors can be a Go `const`.**
