Implementations

source

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

source

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.

source

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

Obtain alternative dependency constraints for this set.

source

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.

source

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

Iterate over packages while also emitting the expression being satisfied.

source

pub fn prune_empty(&mut self)

Prune empty alternatives from this data structure.

Dependency expressions not having any satisfying packages will be removed.
