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