cargo-module — devel/cargo port module

This manual page documents the behavior of setting MODULES=devel/cargo in the ports(7) tree.

Automates download and compilation of dependencies of a Rust project using cargo(1).

During fetch, static dependencies ("crates") listed in MODCARGO_CRATES are downloaded using MODCARGO_DIST_SUBDIR as DIST_SUBDIR.

During post-extract, crates defined in MODCARGO_CRATES are moved to the MODCARGO_VENDOR_DIR directory.

During post-patch, crate-metadata are generated using devel/cargo-generate-vendor.

With CONFIGURE_STYLE set to ‘cargo’, cargo is configured to use MODCARGO_VENDOR_DIR instead of the standard crates-io network source. Finally, any crates listed in MODCARGO_CRATES_UPDATE are updated.

MODCARGO_RUSTFLAGS can be used to pass custom flags to all rustc(1) invocations.

lang/rust is added to MODULES, and devel/cargo-generate-vendor is added to BUILD_DEPENDS.

This module defines:

Path to cargo manifest. Defaults to ${WRKSRC}/Cargo.toml.
Path to Cargo.lock, which is used only by the modcargo-gen-crates target. Defaults to ${MODCARGO_CARGOTOML:toml=lock}.
Crates that will be downloaded by the module.
List of crates to update, overriding the version listed in Cargo.lock.
List of features to be used when building.
List of paths to pass to cargo install instead of .. Needs to be set for some virtual manifests.
Name of the local directory for vendoring crates. Defaults to ${WRKSRC}/modcargo-crates.
Architecture-specific WANTLIB entries required by all Rust code. It is a copy of MODRUST_WANTLIB provided for simplicity.

This module adds three make(1) targets:

Rerun the generation of crates' metadata.
Generate the MODCARGO_CRATES list from Cargo.lock (a preliminary crates list is not required).
Generate the MODCARGO_CRATES list with license information from crates present in the MODCARGO_VENDOR_DIR directory.
