Struct debian_packaging::dependency::SingleDependency

pub struct SingleDependency {
    pub package: String,
    pub version_constraint: Option<DependencyVersionConstraint>,
    pub architectures: Option<(bool, Vec<String>)>,
}

A dependency of a package.

Fields

package: String

Package the dependency is on.

version_constraint: Option<DependencyVersionConstraint>

architectures: Option<(bool, Vec<String>)>

Implementations

impl SingleDependency

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

Parse a single package dependency expression into a SingleDependency.

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

Evaluate whether a package satisfies the requirements of this parsed expression.

This takes as arguments the low-level package components needed for checking.

pub fn package_satisfies_virtual( &self, package: &str, provides: Option<&DependencyVersionConstraint> ) -> bool

Whether a package satisfies a virtual package constraint.

These are processed a bit differently in that architecture doesn’t come into play and version constraints in the source package are optional.

Trait Implementations

impl Clone for SingleDependency

fn clone(&self) -> SingleDependency

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for SingleDependency

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

Formats the value using the given formatter.

impl Display for SingleDependency

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

Formats the value using the given formatter.

impl PartialEq for SingleDependency

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

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

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

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