hardhat/dist/src/internal/builtin-plugins/coverage/helpers/accessors.js

Hardhat is an extensible developer tool that helps smart contract developers increase productivity by reliably bringing together the tools they want.

// NOTE: This file is imported from hot paths — the plugin's `created` hook
// handler and task-actions that may run on every `hardhat test` invocation
// regardless of whether the feature is enabled. It must stay lightweight:
// do not add top-level imports that pull in the coverage-manager module
// graph (debug, node:crypto, file-system traversal, etc.), or the
// `--coverage` lazy-load is silently defeated for every caller.
// If a new helper needs a heavy dependency, put it in a sibling file
// (e.g. `helpers/utils.ts`) so the accessors file's import cost stays flat.
