These options will be used on objects of class 'blob'.
opts_blob(constructor = c("blob", "next"), ...)An object of class <constructive_options/constructive_options_blob>
Depending on constructor, we construct the object as follows:
"blob" (default): Use blob::blob() on a raw object.
"new_blob" (default): Use blob::new_blob() on a list of raw objects.
"as.blob" : Use blob::as_blob() on a character vector
Use opts_raw() and opts_character() to tweak the construction of raw or
character objects constructed as part of the blob construction.
