Module registry 

Automatic registration internals.

Items annotated with #[miniextendr] self-register at link time. The C entrypoint calls registry::miniextendr_register_routines to finalize registration with R. Users don’t interact with this module. Automatic registration for miniextendr.

Every #[miniextendr] item self-registers at link time. package_init() (generated by miniextendr_init!) calls miniextendr_register_routines during R_init_* to finalize registration with R. Users never interact with this module.

Functions

altrep_regs 🔒

call_defs 🔒

Native: read directly from the linkme distributed slice. wasm32: read from a OnceLock populated by install_wasm_runtime_slices.

collect_r_wrappers

Collect all R wrapper entries, sorted by priority and deduplicated.

find_substr 🔒

Find the first occurrence of needle in haystack[from..]. Returns the absolute index in haystack, or None.

has_no_rd_tag 🔒

Check if an R wrapper fragment has @noRd.

has_rdname_tag 🔒

Check if an R wrapper fragment already has an @rdname tag.

inject_rdname 🔒

Inject #' @rdname <value> (and @title if missing) into an R wrapper fragment. Inserts before the first @export/@keywords/@source line, or after the last roxygen line.

memchr 🔒

Find the first byte equal to needle in haystack[from..]. Returns the absolute index, or None.

miniextendr_register_routines^⚠

Register all #[miniextendr] routines and ALTREP classes with R.

miniextendr_write_wasm_registry^⚠

C-callable entry point for wasm_registry.rs generation via cdylib.

miniextendr_write_wrappers^⚠

C-callable entry point for R wrapper generation via cdylib.

normalize_source_locs 🔒

Replace every (<stem>.rs:LINE:COL) occurrence with (<stem>.rs:_:_).

rdname_from_source_file 🔒

Derive an @rdname value from a source file path.

rotate_choices_for_default 🔒

Rotate a comma-separated quoted-choice string so preferred is first.

scan_digits 🔒

Advance past a run of ASCII digits starting at haystack[from]. Returns the absolute index of the first non-digit byte, or None if there are no digits at from (empty run is not valid).

sort_s7_classes 🔒

Sort S7 class definitions so parents come before children.

trait_dispatch 🔒

universal_query^⚠

Universal query function for trait dispatch.

wrappers_semantically_equal 🔒

Returns true when a and b are equal after normalising away (<file>.rs:LINE:COL) positional suffixes in source-attribution comments.

write_r_wrappers_to_file

Write all R wrapper entries to a file.
