Struct BinaryPackageAlternativesResolution 

pub struct BinaryPackageAlternativesResolution<'file, 'data: 'file> {
    pub alternatives: Vec<BinaryPackageSingleDependencyResolution<'file, 'data>>,
}

A collection of BinaryPackageSingleDependencyResolution satisfying a set of alternative expressions.

Fields

alternatives: Vec<BinaryPackageSingleDependencyResolution<'file, 'data>>

Implementations

impl<'file, 'data: 'file> BinaryPackageAlternativesResolution<'file, 'data>

pub fn is_empty(&self) -> bool

Whether no packages satisfy constraints from this list of dependency expressions.

Returns true if the set of dependency expressions is empty or if all expressions have empty packages lists.

pub fn alternative_constraints(&self) -> impl Iterator<Item = &SingleDependency>

Obtain alternative dependency constraints for this set.

pub fn packages( &self, ) -> impl Iterator<Item = &'file BinaryPackageControlFile<'data>> + '_

Iterate over all packages in this set of alternatives.

There may be duplicates in the output stream.

pub fn packages_with_expression( &self, ) -> impl Iterator<Item = (&SingleDependency, &'file BinaryPackageControlFile<'data>)> + '_

Iterate over packages while also emitting the expression being satisfied.

pub fn prune_empty(&mut self)

Prune empty alternatives from this data structure.

Dependency expressions not having any satisfying packages will be removed.
