## Build cache

Cargo shares build artifacts among all the packages of a single workspace.
Today, Cargo does not share build results across different workspaces, but 
a similar result can be achieved by using a third party tool, [sccache].

To setup `sccache`, install it with `cargo install sccache` and set 
`RUSTC_WRAPPER` environmental variable to `sccache` before invoking Cargo.
If you use bash, it makes sense to add `export RUSTC_WRAPPER=sccache` to 
`.bashrc`. Refer to sccache documentation for more details.
