Struct Project 

pub struct Project {
    pub manifest: Manifest,
    pub lock: Option<Lock>,
    pub base: PathBuf,
    pub scope: Scope,
    pub cache: PathBuf,
    pub state: PathBuf,
    pub home: PathBuf,
    /* private fields */
}

A chest.toml with its lock, and the folders its entries go to.

Fields

manifest: Manifest

The manifest.

lock: Option<Lock>

Its lock, when there is one.

base: PathBuf

The manifest’s folder, which its relative paths start from.

scope: Scope

Whether it is a project’s manifest or the user’s global one.

cache: PathBuf

Where git clones are cached and work is staged: ~/.chest/cache unless set otherwise.

state: PathBuf

Where chest records what it placed on this machine, outside any repository: ~/.chest/state unless set otherwise.

home: PathBuf

The canonical home folder, which ~ names.

Implementations

impl Project

pub fn open(path: &Path, scope: Scope) -> Result<Project, ChestError>

The manifest at path and its lock, the file beside it named with .lock for .toml: chest.dev.toml locks in chest.dev.lock.

The manifest’s folder is resolved to its canonical path once, so a project opened through a link or another spelling of its path places, records and removes the same paths. A manifest or lock that is itself a link is refused, as refuse_link says.

pub fn global() -> Result<Project, ChestError>

The user’s global manifest, ~/.chest/chest.toml.

pub fn lock_path(&self) -> PathBuf

Where the lock is.

pub fn root(&self) -> PathBuf

The folder chest never writes outside of: the project’s own for a project manifest, home for the global one.

pub fn store(&self) -> PathBuf

The extension store: [folders] extensions, else .yapi/chest in a project and ~/.chest/store for the global manifest.

pub fn too_wide(&self, folder: &Path, also: &[&Path]) -> bool

Whether folder, an extension’s module root, holds far more than one package, so the extension could load any file there: it is, or holds, the home folder, the agent folder, the filesystem’s root, the manifest’s folder, which is the project’s for a project manifest, the store, which holds the other extensions, or a folder in also. A held folder that does not exist yet counts by the path it will have.

pub fn placed(&self, section: Section, locked: &Locked) -> Vec<PathBuf>

The paths locked occupies: each of its items in each of its section’s folders, or its store folder.

pub fn present(&self, section: Section, locked: &Locked) -> bool

Whether everything locked occupies is there. A link in the first folder, where the copy belongs, counts as missing, as after the folders were reordered. An extension from a path loads where it is, so it always is.

pub async fn sync( &mut self, mode: Mode, npm: &mut Npm, progress: &mut (dyn FnMut(&str) + Send), ) -> Result<Report, ChestError>

Brings the installed entries in line with the manifest and lock as mode says, holding the lock file’s lock and the project’s record lock throughout. Every entry is fetched and checked before anything is put in place, so a failed download changes nothing. Nothing is installed outside Project::root. Only chest’s cache and record, under ~/.chest unless set otherwise, are written elsewhere. progress hears a line for each entry fetched, and one while another chest command holds a lock.

pub fn installed_root(&self, name: &str) -> Option<PathBuf>

The folder installed extension name loads from: its [patch] path, its store folder, the npm package inside it, or its path source. None for an entry that is not an installed extension.

pub fn extension_roots(&self, name: &str) -> Option<(PathBuf, PathBuf)>

Where extension name loads from, as Project::installed_root says whether or not it exists, and the folder that holds the package and its own dependencies, which it may load modules from: the [patch] or path source, or <store>/<name> for git and npm.

pub fn verify(&self) -> Result<Vec<String>, ChestError>

Checks every installed copy of a locked git or npm entry: canonical copies, copy fallbacks and store folders by their hash, and links by what they point to. Returns one line per problem, so none means all match.

pub async fn outdated(&self, npm: &mut Npm) -> Result<Vec<Outdated>, ChestError>

The newest revision each locked git or npm entry’s source offers: the commit its rev names now, or the newest npm version in its range with npm’s latest.

pub async fn fetch_package( &self, entry: &Entry, npm: &mut Npm, ) -> Result<Fetched, ChestError>

Fetches the package entry names, without its dependencies, to read what it provides and requests before it is added: a git source at the commit its rev names, an npm source at the newest version in its range, or a path source where it is.

Trait Implementations
