Struct hua_core::dependency::Requirement

pub struct Requirement { /* private fields */ }

A Requirement to be resolved by the super::DependencyGraph.

Example

use std::collections::BTreeSet;
use semver::VersionReq;
use hua_core::dependency::Requirement;
use hua_core::store::object::Blob;

let mut objects = BTreeSet::new();
objects.insert(Blob::new("bin/bash".into()));

let requirement = Requirement::new("name".to_owned(), VersionReq::parse(">0.0.1")?, objects);

Implementations

impl Requirement

pub fn new(name: String, version_req: VersionReq, objects: BTreeSet<Blob>) -> Self

Creates a new Requirement.

pub fn name(&self) -> &String

Returns the name of the Requirement.

pub fn version_req(&self) -> &VersionReq

Returns the VersionReq of the Requirement.

pub fn blobs(&self) -> &BTreeSet<Blob>

Returns all the Blob of the Requirement.

Trait Implementations

impl<'de> Deserialize<'de> for Requirement

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error> where
    __D: Deserializer<'de>, 

Deserialize this value from the given Serde deserializer.

impl Display for Requirement

impl Ord for Requirement

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

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<Requirement> for Requirement

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=.

impl PartialOrd<Requirement> for Requirement

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Requirement

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