Struct Package 

pub struct Package {
    pub name: String,
}

A Python package identifier

Fields

name: String

Normalized package name

Implementations

impl Package

pub fn new(name: impl Into<String>) -> Self

Create a new package with normalized name

Trait Implementations

impl Borrow<str> for Package

fn borrow(&self) -> &str

Immutably borrows from an owned value.

impl Clone for Package

fn clone(&self) -> Package

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Package

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

Formats the value using the given formatter.

impl DependencyProvider<Package, Version> for PyPIProvider

fn choose_package_version<T: Borrow<Package>, U: Borrow<Range<Version>>>( &self, potential_packages: impl Iterator<Item = (T, U)>, ) -> Result<(T, Option<Version>), Box<dyn StdError>>

Decision making is the process of choosing the next package and version that will be appended to the partial solution. Every time such a decision must be made, potential valid packages and version ranges are preselected by the resolver, and the dependency provider must choose.

fn get_dependencies( &self, package: &Package, version: &Version, ) -> Result<Dependencies<Package, Version>, Box<dyn StdError>>

Retrieves the package dependencies. Return Dependencies::Unknown if its dependencies are unknown.

fn should_cancel(&self) -> Result<(), Box<dyn Error>>

This is called fairly regularly during the resolution, if it returns an Err then resolution will be terminated. This is helpful if you want to add some form of early termination like a timeout, or you want to add some form of user feedback if things are taking a while. If not provided the resolver will run as long as needed.

impl<'de> Deserialize<'de> for Package

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for Package

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

Formats the value using the given formatter.

impl Hash for Package

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for Package

fn cmp(&self, other: &Self) -> 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 Package

fn eq(&self, other: &Package) -> 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 Package

fn partial_cmp(&self, other: &Self) -> 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 Package

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for Package
