rust-sha3 was recently updated to version 0.12 and a
rust-sha3-0.10 package was introduced. The debian
depdencies for your package allow the new version
but the cargo dependencies do not.

I have prepared a patch which relaxes the cargo
dependencies on sha3 and have tested that the
package builds and the autopkgtests pass with the
new version. I have also looked at the upstream
changelog for the sha3 crate and I do not see
anything too scary.

Alternatively if you want to remain on the old
version of the sha3 crate, please change
your (build-)dependencies to
librust-sha3-0.10+default-dev

Peter Green writes ("Bug#1141136: rust-derive-deftly - please select a version of sha3 crate."):

This dependency was relexed upstream in 1.11.2.  The fix is to upload
the latest upstream version, 1.11.3.  I will do that.

Ian.
