Struct cargo::ops::cargo_generate_lockfile::PackageDiff

pub struct PackageDiff {
    removed: Vec<PackageId>,
    added: Vec<PackageId>,
    unchanged: Vec<PackageId>,
}

All resolved versions of a package name within a SourceId

Fields

removed: Vec<PackageId>

added: Vec<PackageId>

unchanged: Vec<PackageId>

Implementations

impl PackageDiff

pub fn new(resolve: &Resolve) -> Vec<Self>

pub fn diff(previous_resolve: &Resolve, resolve: &Resolve) -> Vec<Self>

fn key(dep: PackageId) -> (&'static str, SourceId)

pub fn change(&self) -> Option<(&PackageId, &PackageId)>

Guess if a package upgraded/downgraded

All PackageDiff knows is that entries were added/removed within Resolve. A package could be added or removed because of dependencies from other packages which makes it hard to definitively say “X was upgrade to N”.

pub fn alternatives_query(&self) -> Option<Dependency>

For querying PackageRegistry for alternative versions to report to the user

Trait Implementations

impl Clone for PackageDiff

fn clone(&self) -> PackageDiff

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PackageDiff

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

Formats the value using the given formatter.

impl Default for PackageDiff

fn default() -> PackageDiff

Returns the “default value” for a type.

Layout

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
