Module fs 

The filesystem seam (spec/sync/README.md §4.2): the walk over .md files — each directory’s entries in bytewise order of their names, depth-first (§9: Node’s readdir sorts through libuv, so a port whose listing is unsorted sorts) — (mtime_ns, size) stats and reads, behind a trait so the sweep’s I/O stays out of the fixtures. A real implementation over std::fs and an in-memory one over a flat path map that walks the same way.

Structs

FileStat

A file’s cheap change token.

MemFile

One in-memory file.

MemFileSystem

An in-memory filesystem (the fixture runner’s): files keyed by repo-relative path; the walk treats the /-separated paths as a directory tree and visits each directory’s entries in bytewise name order, depth-first, exactly as RealFileSystem does (§4.2). The root argument is ignored.

RealFileSystem

The operating system’s filesystem.

Constants

IGNORED_DIRS

The directory names the walk skips.

Traits

FileSystem

Where the fast path’s bytes come from. Paths are repo-relative with / separators; every method takes the repo root.

Functions

is_ignored_dir

Whether a directory entry name is one the walk skips.
