replace directive (#346)
Browse files Browse the repository at this point in the history
Adds a `replace` directive that makes it easier to serialize foreign types.

Example usage with github.com/google/uuid

  ```go
  package main

  import "github.com/google/uuid"

  //go:generate msgp

  //msgp:replace uuid.UUID with:UUID
  type UUID [16]byte

  // Or like that
  //msgp:replace uuid.UUID with:[16]byte

  type User struct {
    ID uuid.UUID
  }
  ```
