Struct Dependency 

pub struct Dependency {
    pub name: String,
    pub required_version: String,
    pub features: Vec<String>,
    pub optional: bool,
    pub default_features: bool,
    pub target: Option<String>,
    pub kind: Option<DependencyKind>,
    pub package: Option<String>,
}

A single dependency of a specific crate version

Fields

name: String

The crate name

required_version: String

The version the parent crate requires of this dependency

features: Vec<String>

All cargo features configured by the parent crate

optional: bool

True if this is an optional dependency

default_features: bool

True if default features are enabled

target: Option<String>

The name of the build target

kind: Option<DependencyKind>

The kind of dependency, usually ‘normal’ or ‘dev’

package: Option<String>

The package this crate is contained in

Implementations

impl Dependency

pub fn required_version(&self) -> VersionReq

Parse and return this dependency’s semantic version requirement as semver::VersionReq.

Panics

Panics if self.required_version is not a valid SemVer requirement.

Cargo and crates.io enforce SemVer compliance for dependencies when a crate is published or updated. Nevertheless, our index contains a small number of releases whose dependency requirements are not valid SemVer (currently 14 out of ~1.8M).

Trait Implementations

impl Clone for Dependency

fn clone(&self) -> Dependency

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Dependency

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Dependency

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Dependency

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 Dependency

fn cmp(&self, other: &Dependency) -> 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 Dependency

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

fn partial_cmp(&self, other: &Dependency) -> 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 Dependency

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 Dependency

impl StructuralPartialEq for Dependency
