Environment variables Cargo sets for build scripts

Fields

cargo: PathBuf

Path to the cargo binary performing the build.

cargo_manifest_dir: PathBuf

The directory containing the manifest for the package being built (the package containing the build script). Also note that this is the value of the current working directory of the build script when it starts.

cargo_manifest_links: Option<OsString>

The manifest links value.

cargo_cfg_unix: bool

Set on unix-like platforms.

cargo_cfg_windows: bool

Set on windows-like platforms.

cargo_cfg_target_family: String

The target family (windows, unix)

cargo_cfg_target_os: String

The target operating system (windows, macos, ios, linux, android, freebsd, dragonfly, openbsd, netbsd, ...)

cargo_cfg_target_arch: String

The CPU target architecture (x86, x86_64, mips, powerpc, powerpc64, arm, aarch64, ...)

cargo_cfg_target_vendor: String

The target vendor (apple, fortanix, pc, unknown, ...)

cargo_cfg_target_env: String

The target environment ABI (blank, gnu, msvc, musl, sgx, ...)

cargo_cfg_target_pointer_width: String

The CPU pointer width (16, 32, 64, ...)

cargo_cfg_target_endian: String

The CPU target endianness (little, big, ...)

cargo_cfg_target_features: BTreeSet<String>

List of CPU target features enabled (avx, avx2, crt-static, rdrand, sse, sse2, sse4.1, ...)

out_dir: PathBuf

The folder in which all output should be placed

target: String

The target triple that is being compiled for (x86_64-pc-windows-msvc, ...)

host: String

The host triple of the rust compiler / build scripts (x86_64-pc-windows-msvc, ...)

num_jobs: String

The parallelism specified as the top-level parallelism.

opt_level: String

Values of the corresponding variables for the profile currently being built (DEBUG, ...)

profile: String

release for release builds, debug for debug builds, custom profiles may add more values

rustc: PathBuf

The compiler cargo has resolved to use

rustdoc: Option<PathBuf>

The documentation generator cargo has resolved to use

rustc_linker: Option<PathBuf>

The linker binary that Cargo has resolved to use for the current target, if specified
