Expand description
Read-only reader for installed-package metadata, help databases, and selected CRAN-like repository indexes in R’s RDS serialization format.
parse reads a decompressed XDR serialization stream. file provides
the bounded standalone-file entry layer, including supported compression
envelopes.
See the crate README for the concrete repository-index profiles covered by deterministic fixtures and verified manually against real files.
This crate is scoped to installed-R-package information and selected
CRAN-like repository indexes. Unknown SEXP
values are hard errors, never silently accepted. RObject/RValue are a
supported advanced API with encapsulated fields and non-exhaustive enums;
consumers must include wildcard match arms. The typed package views and
general matrix::CharacterMatrix view are the stable convenience surface.
parse accepts only decompressed XDR,
while file::from_bytes accepts raw XDR, gzip, xz, bzip2, and zstd
envelopes when enabled. Default resource limits are depth 5,000, vectors
8,000,000 elements, 16,000,000 total elements, and 256 MiB file inputs.
