Development and Vendoring • Rsassy

Rsassy builds a small Rust crate during package installation. That crate depends on sassy for approximate matching and needletail for chunked FASTA/FASTQ iteration.

sassy = { version = "0.2.1", default-features = false }
needletail = { version = "0.6.3", default-features = false, features = ["flate2"] }

Only needletail’s gzip path is enabled by default; bzip2, xz, and zstd support are intentionally not enabled unless the package chooses to expand compression support later.

Vendoring

Rust sources are installed from the vendored bundle. Refresh it after Rust dependency changes:

make vendor-rust

This updates:

src/rust/vendor.tar.xz
inst/AUTHORS
inst/LICENCE.note

Package installation then runs Cargo in offline mode.

Development commands

make rd       # regenerate NAMESPACE and man/*.Rd
make readme   # regenerate README.md
make install  # local install
make test     # tinytest
make check    # R CMD build + R CMD check
make reports  # render committed benchmark/conformance markdown reports
make clean    # remove build artifacts

make check uses two Cargo jobs by default. For local builds:

make CARGO_JOBS=10 check

R build hooks

configure / configure.win generate src/Makevars files.
src/Makevars.in / src/Makevars.win.in build the Rust libraries.
src/install.libs.R installs backend libraries under backends/.
cleanup removes generated files.
