perl-module-boundary

Detect standalone Perl module tokens at lexical boundaries.

This crate answers a narrow question: does a line contain a module token that is truly standalone, or is it part of a larger identifier or path? That makes it the boundary-checking layer for import, reference, and rename workflows.

Pipeline

• perl-module-token-core parses the token span.
• perl-module-boundary filters that span down to standalone matches.
• perl-module-import, perl-module-reference, and perl-module-rename use the result to avoid partial matches.

API

• ModuleTokenRange
• ModuleTokenRangeIter
• find_standalone_module_token_ranges
• contains_standalone_module_token

Example

use perl_module_boundary::{contains_standalone_module_token, find_standalone_module_token_ranges};

let line = "use Foo::Bar;";
assert!(contains_standalone_module_token(line, "Foo::Bar"));
assert_eq!(find_standalone_module_token_ranges(line, "Foo::Bar").count(), 1);
