Some more rust/cargo insights

[Hartmut Goebel]

Hi.,

these day I had spent some more hours struggling with rust ans cargo, 
trying to get "pre-built" crates.

Summery; Cargo is cruft, no solution found yet.

I tried reusing a crate from the very same place it was built (see 
enclosed script). Anyhow, this does not work since cargo uses a 
different "metadata" value, even if noting changed. Based in the verbose 
output (cargo build -v …) I assume that some parameters of the 
"destination" build get included into this value.

This meets another observation; when building the sequoia suite, several 
crates are build several times - even if all builds are performed in the 
same environment.

Rust's build system is such a cruft - I really would like to throw it 
where it belongs: into the trash.
