Trait Implementations

impl PackageManager for Npm

fn name(&self) -> String

Returns the name of this package manager. This is a unique all-lowercase identifier that should not conflict with any others. It’s common to make this the name of the crate, without the darling- prefix. For example, this could return "example".to_owned(), and the crate would be called darling-example.

fn install(&self, _context: &Context, package: &InstallationEntry) -> Result<()>

Installs a package with the given version. If no version is supplied, this should install the latest version. Note that this does not affect the cache file. This simply supplies the system package install command.

fn uninstall( &self, _context: &Context, package: &InstallationEntry, ) -> Result<()>

Uninstalls a package from the system. This does not affect the cache file, it simply removes the package from the system itself, and darling-core will handle removing the package from the cache file.

fn get_all_explicit(&self, _context: &Context) -> Result<Vec<(String, String)>>

Returns all explicitly installed packages on the system; That is, packages which are not dependencies of other packages. This should not read from a darling file; Instead, darling uses this method to update the file when running darling require-all

fn post_install(&self, _context: &Context) -> Result<(), Error>

This is run after a single or group of packages are installed. The difference between placing code here and in [install] is that when running commands like load-installed, which load all installed packages into the darling config file, this is only run once after all packages are installed, instead of every time an individual package is installed.
