Struct ResolvedPackages 

pub struct ResolvedPackages { /* private fields */ }

Collection of resolved packages from a lock file.

Provides efficient lookup of resolved versions by package name.

Examples

use deps_core::lockfile::{ResolvedPackages, ResolvedPackage, ResolvedSource};

let mut packages = ResolvedPackages::new();
packages.insert(ResolvedPackage {
    name: "serde".into(),
    version: "1.0.195".into(),
    source: ResolvedSource::Registry {
        url: "https://github.com/rust-lang/crates.io-index".into(),
        checksum: "abc123".into(),
    },
    dependencies: vec!["serde_derive".into()],
});

assert_eq!(packages.get_version("serde"), Some("1.0.195"));
assert_eq!(packages.len(), 1);

Implementations

impl ResolvedPackages

pub fn new() -> Self

Creates a new empty collection.

pub fn insert(&mut self, package: ResolvedPackage)

Inserts a resolved package.

If a package with the same name already exists, it is replaced.

pub fn get(&self, name: &str) -> Option<&ResolvedPackage>

Gets a resolved package by name.

Returns None if the package is not in the lock file.

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

Gets the resolved version string for a package.

Returns None if the package is not in the lock file.

This is a convenience method equivalent to get(name).map(|p| p.version.as_str()).

pub fn len(&self) -> usize

Returns the number of resolved packages.

pub fn is_empty(&self) -> bool

Returns true if there are no resolved packages.

pub fn iter(&self) -> impl Iterator<Item = (&String, &ResolvedPackage)>

Returns an iterator over package names and their resolved info.

pub fn into_map(self) -> HashMap<String, ResolvedPackage>

Converts into a HashMap for easier integration.

Trait Implementations

impl Clone for ResolvedPackages

fn clone(&self) -> ResolvedPackages

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ResolvedPackages

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for ResolvedPackages

fn default() -> ResolvedPackages

Returns the “default value” for a type.
