`tools-path-dep-repair`

Repairs stale `path = "..."` dependency values in Cargo manifests after crates move (the tier refactor renamed crates/forge-<x> to crates/<tier>/<x>). Reads the package-name -> directory index from the manifests that exist now, rewrites only path values that no longer resolve on disk, and reports any dep it cannot resolve instead of guessing. Standalone example workspaces (examples/*) are the class of victim: they carry their own lockfile and are not built by `cargo build --workspace`, so a moved crate breaks them silently.

What it is for

Pure repair logic: given a manifest's text, its directory, a package-name -> directory index, and a path-existence oracle, produce the repaired text plus the list of changes and unresolved deps.

Everything decidable is a pure function (Gate 2.1); the only fs work lives in main.rs (walking the tree, reading/writing files).

Capabilities

`crate root`

Pure repair logic: given a manifest's text, its directory, a package-name ->

Item
`fn package_name(manifest : & str) -> Option <String>`
`fn dep_table_header(line : & str) -> Option <String>`
`fn relative_path(from_dir : & Path, to : & Path) -> String`

`Change`

Pure repair logic: given a manifest's text, its directory, a package-name ->

Item
`pub struct Change`

`PackageIndex`

Pure repair logic: given a manifest's text, its directory, a package-name ->

Item
`pub struct PackageIndex`
`PackageIndex :: fn insert(& mut self, name : impl Into <String>, dir : impl Into <PathBuf>)`
`PackageIndex :: fn get(& self, name : & str) -> Option <& Path>`
`PackageIndex :: fn len(& self) -> usize`
`PackageIndex :: fn is_empty(& self) -> bool`

`PathDep`

Pure repair logic: given a manifest's text, its directory, a package-name ->

Item
`pub struct PathDep`
`fn parse_path_dep(line : & str, section_dep : Option <& str>) -> Option <PathDep>`

`Repair`

Pure repair logic: given a manifest's text, its directory, a package-name ->

Item
`pub struct Repair`
`fn repair(manifest : & str, manifest_dir : & Path, index : & PackageIndex, exists : & dyn Fn(& Path) -> bool,) -> Repair`

`Unresolved`

Pure repair logic: given a manifest's text, its directory, a package-name ->

Item
`pub struct Unresolved`

How to use it

No examples/ target and no doctest in this crate's rustdoc. The tests listed under Verification are the closest executable usage.

Module structure

No public modules: the crate root is its whole surface.

Public surface

`crate root`

Item	What it is
`pub struct PackageIndex`	package name -> absolute directory holding its `Cargo.toml`.
`PackageIndex :: fn insert(& mut self, name : impl Into <String>, dir : impl Into <PathBuf>)`	—
`PackageIndex :: fn get(& self, name : & str) -> Option <& Path>`	—
`PackageIndex :: fn len(& self) -> usize`	—
`PackageIndex :: fn is_empty(& self) -> bool`	—
`fn package_name(manifest : & str) -> Option <String>`	`name = "..."` from the `package` section
`pub struct Change`	—
`pub struct Unresolved`	—
`pub struct Repair`	—
`fn repair(manifest : & str, manifest_dir : & Path, index : & PackageIndex, exists : & dyn Fn(& Path) -> bool,) -> Repair`	Rewrite every `path = "..."` whose target does not exist, when the dependency name is in `index`
`pub struct PathDep`	One `path = "..."` dependency as written in a manifest
`fn parse_path_dep(line : & str, section_dep : Option <& str>) -> Option <PathDep>`	The dep a `path = "..."` line declares, or `None` for any other line
`fn dep_table_header(line : & str) -> Option <String>`	`dependencies.foo`, `dev-dependencies.foo`, `target.'cfg(x)'.dependencies.foo`.
`fn relative_path(from_dir : & Path, to : & Path) -> String`	A `..`-relative path from `from_dir` to `to`, in forward-slash form for TOML.

No pub use re-exports: every item above is declared in this crate.

Boundary

Depends on no other workspace tier.

Shares tier tools with 84 other crates: tools-advisory-reach, tools-archive-guard, tools-artifact-scaffold, tools-ask-ai-core, tools-ask-ais, tools-ask-gemini, tools-book, tools-book-report, … (84 total).

_What this crate deliberately does NOT own is a judgment. No committed registry records one for it, so none is stated here._

Feature flags

No Cargo features are defined: every capability is unconditional, so no consumer can receive a half-wired crate.

Targets

Kind	Name	Source

Error model

No public error type was detected: no public item declares a type named *Error, and no public signature returns one.

Operational characteristics

Property	Evidence
async public surface	none detected
async runtime	none detected
database access	none detected
network I/O	none detected
unsafe code	none detected
environment variables	none detected

No unsafe block, unsafe fn, unsafe impl or unsafe trait was found by the parser anywhere in this crate's source.

Configuration

No environment variable is read with a literal name anywhere in this crate. A variable whose key is computed at run time cannot be listed here, and is not claimed to be absent.

1 workspace crate depends on this one: tools-crate-retarget.
