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.
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. Alternatively, you can set
build.rustc-wrapper in the
Cargo configuration. Refer to sccache documentation for more
