Module crate_index 

Shared crate index built from a single parse pass over all source files.

All lint rules operate on this index rather than re-parsing files.

Structs

AttributedTraitImpl

CrateIndex

Shared parsed state for all lint rules.

FileData

HandBuilt 🔒

The types a file builds ExternalPtrs of itself (MXL121), in any item:

ImplMethodEntry

Per-method data collected during the crate-index pass for impl-method lint rules.

IndexError

Why CrateIndex::build failed, with the source files it had found.

InherentImpl

An inherent #[miniextendr] impl block, for the rules that look at a type across all its impl blocks (MXL121).

LintItem

ModDir 🔒

Where the mod declarations of one scope resolve, tracked as rustc does (rustc_expand::module).

Enums

LintKind

MethodReceiverKind

Receiver kind for an impl method, mirroring ReceiverKind in miniextendr-macros.

Constants

INTO_SEXP_CALLS 🔒

into_sexp call spellings that build a fresh, unprotected SEXP.

NONAPI_ATTRIB_FNS 🔒

R’s non-API attribute-pairlist accessors. R CMD check (R >= 4.6) reports them.

RAW_R_EVAL_FNS 🔒

R entry points that run R code, or R’s interrupt handling, and longjmp out on an R error or a pending interrupt.

RF_ERROR_PATTERNS 🔒

Patterns that indicate direct Rf_error/Rf_errorcall calls in user code.

Functions

block_lines 🔒

The 1-based lines of block’s { and }.

called_idents 🔒

The whole identifiers in code that a ( follows (after optional whitespace): the names of the functions it calls or declares. DUPLICATE_ATTRIB( yields DUPLICATE_ATTRIB, never ATTRIB.

collect_active_cargo_features 🔒

Collect the set of active Cargo features from CARGO_FEATURE_* env vars. Feature names are normalized: CARGO_FEATURE_FOO_BAR → "foo-bar".

collect_doc_pkg_links 🔒

Record the pkg::topic links in the docs of a #[miniextendr] item and, for an impl block, of its methods.

collect_items_recursive 🔒

Recursively collect all lint-relevant information from parsed items.

collect_returned_types 🔒

Add to out the type ty hands to R as a class object: its last path segment, self_type for Self, through Result, Option and ExternalPtr. Other names (i32, Vec, …) are added too; they match no class.

collect_rs_files_from_module_tree 🔒

Collect Rust source files by walking the module tree from the crate root, following mod child; declarations and respecting #[cfg(feature = "...")] gates via CARGO_FEATURE_* environment variables.

detect_receiver_kind 🔒

Detect the receiver kind from a method signature.

discover_mod_declarations 🔒

Walk parsed items looking for mod child; declarations and recurse.

eval_cfg_str 🔒

Try to evaluate a single cfg string like cfg(feature = "foo").

extract_feature_name 🔒

Extract the feature name from a string like feature="foo".

extract_param_names 🔒

Extract named parameter names (and their 1-based line numbers) from a function signature.

extract_return_type_str 🔒

Stringify a syn::ReturnType to a compact token string.

has_constructor_attr 🔒

Returns true when the attribute list contains #[miniextendr(constructor)] or #[miniextendr(r6(constructor))] / #[miniextendr(s3(constructor))] etc.

header_allows 🔒

Whether // mxl::allow(<code>) is on an item’s header: its lines first_line..=line (1-based: attributes, doc comments and the item’s own first line) or the line above them.

is_cfg_active 🔒

Evaluate whether a set of #[cfg(...)] attributes is active given the current features.

is_external_ptr_new 🔒

Whether path ends in ExternalPtr::new or ExternalPtr::new_unchecked, with or without a turbofish.

is_suppressed 🔒

Check if a lint code is suppressed via // mxl::allow(MXL...) comment.

line_has_allow 🔒

Check if a single line contains // mxl::allow(...) matching the given code.

parse_file 🔒

path_type_name 🔒

The type path names: its last segment, self_type for Self.

scan_ffi_unchecked_calls 🔒

Scan raw source text for sys::*_unchecked() calls.

scan_nonapi_attrib_calls 🔒

Scan raw source text for calls to, or declarations of, ATTRIB / SET_ATTRIB and their _unchecked forms.

scan_raw_r_eval_calls 🔒

Scan the FileData::miniextendr_bodies for calls to Rf_eval, R_forceAndCall, Rf_applyClosure and R_CheckUserInterrupt, and their _unchecked forms, through any path (sys::Rf_eval(, miniextendr_api::sys::Rf_eval(, an imported Rf_eval().

scan_rf_error_calls 🔒

Scan raw source text for direct Rf_error/Rf_errorcall calls.

scan_vec_into_sexp_calls 🔒

Scan raw source text for into_sexp() / into_sexp_unchecked() calls that appear inside a vec! or &[...] literal — the use-after-free idiom (#307, #1025).

self_handle_ty 🔒

The handle ty names over Self: "ExternalPtr" for ExternalPtr<Self>, "ExternalPtrRef" / "ExternalPtrMut" for the views (ExternalPtrRef<'_, Self>), matched on the last path segment with a Self type argument.

walk_module_file 🔒

Recursively walk a module file, following mod declarations.
