CARGO-MODULE(5)

NAME
cargo-module - devel/cargo port module

DESCRIPTION
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, devel/cargo and devel/cargo-generate-vendor are added to BUILD_DEPENDS. By default MASTER_SITES9 is used to download the crates.

This module defines:

MODCARGO_CARGOTOML
    Path to cargo manifest. Defaults to ${WRKSRC}/Cargo.toml.

MODCARGO_CRATES
    Crates that will be downloaded by the module.

MODCARGO_CRATES_UPDATE
    List of crates to update, overriding the version listed in Cargo.lock.

MODCARGO_FEATURES
    List of features to be used when building.

MODCARGO_VENDOR_DIR
    Name of the local directory for vendoring crates. Defaults to ${WRKSRC}/modcargo-crates.

This module adds three make(1) targets:

modcargo-metadata
    Rerun the generation of crates' metadata.

modcargo-gen-crates
    Generate the MODCARGO_CRATES list from Cargo.lock (a preliminary crates list is not required).

modcargo-gen-crates-licenses
    Generate the MODCARGO_CRATES list with license information from crates present in the MODCARGO_VENDOR_DIR directory.
