Struct Lockfile 

pub struct Lockfile {
    pub version: u64,
    pub packages: Vec<LockedPackage>,
}

A parsed package-lock.json.

Fields

version: u64

The lockfileVersion (always ≥ 2 here).

packages: Vec<LockedPackage>

Every entry of the packages map, sorted by key — so install order, and thus .bin name-collision resolution, is deterministic. Includes the root "" entry.

Implementations

impl Lockfile

pub fn parse(s: &str) -> Result<Lockfile, Box<dyn Error>>

Parse a package-lock.json document (lockfileVersion 2 or 3).

pub fn installable(&self, host_os: &str, host_arch: &str) -> Vec<&LockedPackage>

The entries an npm-tarball installer fetches on the given host: real (non-root) node_modules/… packages that aren’t links and whose os/cpu match. host_os and host_arch are Rust’s std::env::consts::{OS, ARCH} spellings. Whether each entry’s resolved is actually an http(s) registry tarball is left to the caller — see LockedPackage::is_registry_tarball.
