This article provides Article description::an introduction to using or  on Gentoo, optimizing compiled code using safe, sane RUSTFLAGS.

RUSTFLAGS
rustc --print target-cpus

Cargo configuration
Cargo can also be configured through environment variables. For each configuration key of the form foo.bar the environment variable CARGO_FOO_BAR can also be used to define the value. For example the build.jobs key can also be defined by CARGO_BUILD_JOBS.

Environment variables will take precedent over TOML configuration, and currently only integer, boolean, and string keys are supported to be defined by environment variables.
