as_blob(NA_character_) returns a missing blob instead of as_blob("NA") (#26, @michaelchirico).is_vector_s3() (#19).vec_ptype2.hms.default() forwards to vec_default_ptype2() for compatibility with vctrs 0.2.1.The blob class is now based on list_of(raw()) from the vctrs package (#11). This adds support for vec_cast() and vec_ptype2(). Some operations (such as subset assignment) are now stricter. The new_blob() constructor permits safe and fast construction of blob objects from a list, and validate_blob() checks an existing object for conformity with the rules.
The new is_blob() deprecates the existing is.blob(). as.blob() is deprecated in favor of vec_cast() or the new as_blob() (which is just a thin wrapper around vec_cast()).
Indexing a vector of blobs out of bounds now raises an error. Use NA as index to create a NULL blob.
Now suggesting pillar instead of importing tibble, and using colored
formatting with the prettyunits package with B instead of b as units
(#7, #9).
The blob class can now be used for S4 dispatch.
Calling c() on blob objects returns a blob.
New maintainer: Kirill Müller.
Added as.blob.blob()and as.data.frame.blob() methods (#3).
Size of very large blobs is displayed correctly.
