Bug#907629: librsvg: Embedded code copies: assorted Rust libraries

[Simon McVittie]

Source: librsvg
Version: 2.44.1-1
Severity: normal
Tags: help

librsvg contains "vendored" copies of various Rust libraries. Ideally
we would use the vendored copy or the system copy of each library,
whichever is (compatible and) newer, but I don't know enough Rust to
know how to do that (and set the right Built-Using) for a package that
is not built with dh-cargo.

We can't use dh-cargo because the Rust code here is only part of a larger
package that uses an Autotools build system.

Some of the vendored libraries are available in Debian, others are not:

Some of the vendored libraries are only there as developer dependencies,
but "cargo test" requires that we have them anyway, as far as I can see.
Perhaps the solution is to not run "cargo test"; I don't know.
