Safe Functions

These functions are actually completely safe, but they are defined here because they are used by typeclass instances. Import them from Data.ByteArray.Builder instead.

stringUtf8 :: String -> Builder

Create a builder from a cons-list of Char. These are be UTF-8 encoded.

cstring :: CString -> Builder

Create a builder from a NUL-terminated CString. This ignores any textual encoding, copying bytes until NUL is reached.
