Struct LockedPackage 

pub struct LockedPackage {
    pub name: PackageName,
    pub version: Version,
    pub digest: Digest,
    pub registry: RegistryUri,
    pub repository: String,
    pub dependencies: Vec<LockedDependency>,
    pub dependants: usize,
}

Captures immutable metadata about a given package

It is used to ensure that future installations will use the exact same dependencies.

Fields

name: PackageName

The name of the package

version: Version

The exact version of the package

digest: Digest

The cryptographic digest of the package contents

registry: RegistryUri

The URI of the registry that contains the package

repository: String

The identifier of the repository where the package was published

dependencies: Vec<LockedDependency>

Names of dependency packages

dependants: usize

Count of dependant packages in the current graph

This is used to detect when an entry can be safely removed from the lockfile.

Implementations

impl LockedPackage

pub fn lock( package: &Package, registry: RegistryUri, repository: String, dependants: usize, ) -> Self

Captures the source, version and checksum of a Package for use in reproducible installs

pub fn validate(&self, package: &Package) -> Result<()>

Validates if another LockedPackage matches this one

Trait Implementations

impl Clone for LockedPackage

fn clone(&self) -> LockedPackage

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for LockedPackage

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LockedPackage

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Eq for LockedPackage

impl From<&LockedPackage> for FileRequirement

fn from(package: &LockedPackage) -> Self

Converts to this type from the input type.

impl From<LockedPackage> for FileRequirement

fn from(package: LockedPackage) -> Self

Converts to this type from the input type.

impl FromIterator<LockedPackage> for PackageLockfile

fn from_iter<I: IntoIterator<Item = LockedPackage>>(iter: I) -> Self

Creates a value from an iterator.

impl FromIterator<LockedPackage> for WorkspaceLockfile

This converts the results of package install to a workspace lockfile

fn from_iter<I: IntoIterator<Item = LockedPackage>>(iter: I) -> Self

Creates a value from an iterator.

impl Ord for LockedPackage

fn cmp(&self, other: &LockedPackage) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for LockedPackage

fn eq(&self, other: &LockedPackage) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd for LockedPackage

fn partial_cmp(&self, other: &LockedPackage) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

impl Serialize for LockedPackage

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
