|
|
// It returns the error unchanged, useful in functional composition where

|
// an error needs to be passed through without modification.

|
|
// Example:
|
|
//
|
|
// err := errors.New("something went wrong")
|
|
// same := Identity(err) // returns the same error
|
|
var Identity = F.Identity[error]
