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

impl PartialEq<SingleDependency> 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: &SingleDependency) -> bool

This method tests for !=.
