std::fs

This is the canonical module doc for std::fs.

std::fs provides the hosted filesystem API shipped in std/fs.slk: low-level file handles, stat-style metadata queries (stat, lstat, fstat, Stats), whole-file helpers, directory iteration, and path-based mutation primitives, all backed by std::runtime::fs.

Hosted package build modules may use the same Dir.next() and borrowed Dir.next_view() iteration APIs as ordinary executables. Optional DirEntryViewResult bindings and loops retain their normal semantics inside the compiler-generated build-module wrapper.

The detailed API contract and platform notes are documented in:

• filesystem
