Struct DependencyList 

pub struct DependencyList { /* private fields */ }

Represents an ordered list of dependencies, delimited by commas (,).

Implementations

impl DependencyList

pub fn parse(s: &str) -> Result<Self>

Parse a dependency list from a string.

A dependency list is a comma-delimited list of expressions. Each expression is a | delimited list of expressions of the form package (version_relationship version) [arch].

pub fn package_satisfies( &self, package: &str, version: &PackageVersion, arch: &str, ) -> bool

Evaluate whether a package satisfies at least one expression in this list.

pub fn requirements(&self) -> impl Iterator<Item = &DependencyVariants>

Obtain the individual requirements constituting this list of dependencies.

Each requirement is itself a set of expressions to match against. The length of this set is commonly 1.

Trait Implementations

impl Clone for DependencyList

fn clone(&self) -> DependencyList

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DependencyList

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

Formats the value using the given formatter.

impl Display for DependencyList

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

Formats the value using the given formatter.

impl PartialEq for DependencyList

fn eq(&self, other: &DependencyList) -> 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.
