Thanks for investigating and sorry for blocking other packages.

Interesting, I will look into packaging this instead next week.

Huh, I get a number of rdeps (in Debian unstable):

$ apt rdepends librust-sha3-0.9-dev
librust-sha3-0.9-dev
Reverse Depends:
   Depends: librust-sha3-0.9+std-dev (= 0.9.1-2)
   Depends: librust-multihash-dev

$ build-rdeps librust-sha3-0.9-dev
Reverse Build-depends in main:
------------------------------

rust-cid
rust-cid-npm
rust-coreutils
rust-ipfs-unixfs
rust-multihash

Found a total of 5 reverse build-depend(s) for librust-sha3-0.9-dev.

Or by asking dak:

$ ssh coccia.debian.org dak rm -nR rust-sha3-0.9
Will remove the following packages from unstable:

librust-sha3-0.9+std-dev |    0.9.1-2 | amd64, arm64, armel, armhf, i386, mips64el, mipsel, ppc64el, s390x
librust-sha3-0.9-dev |    0.9.1-2 | amd64, arm64, armel, armhf, i386, mips64el, mipsel, ppc64el, s390x
rust-sha3-0.9 |    0.9.1-2 | source

Maintainer: Debian Rust Maintainers <pkg-rust-maintainers at alioth-lists.debian.net>

------------------- Reason -------------------

----------------------------------------------

Checking reverse dependencies...
# Broken Depends:
rust-multihash: librust-multihash-dev [amd64 arm64 armel armhf i386 mips64el mipsel ppc64el s390x]

# Broken Build-Depends:
rust-multihash: librust-sha3-0.9-dev

Dependency problem found.

>1: I close that delete request and prepare an upload of block-padding-0.2
>
>2: I file additional delete requests on the whole dependency chain up to cid-npm

Neither of them are needed. rust-sha3-0.9 will be removed from testing 
due to #1042195 (currently scheduled for August 23.) at which point 
block-padding should migrate.

Again sorry for blocking the package and I will try to work on it.

Cheers Jochen
