error: failed to parse manifest at

Caused by:
failed to parse the `edition` key
Caused by:
this version of Cargo is older than the `2021` edition, and only supports
`2015` and `2018` editions.
----------------------------------------------------------------------
nbdkit itself uses edition = 2018, but this seems to affects one of
the dependencies.
I'm not sure how to solve this, but one ideas I had is in ./configure
to check if the cargo/rust we're trying to use doesn't support some
base edition (eg. latest edition supported < 2021) then we would
disable rust bindings.
Unfortunately actually getting the latest supported edition seems
hard. The best I could find is parsing this which doesn't seem ideal:
$ rustc --help |& grep -- --edition
--edition 2015|2018|2021|2024
What do you think?
Rich.
