pub struct Preferences(/* private fields */);Expand description
A set of pinned packages that should be preserved during resolution, if possible.
The marker is the marker of the fork that resolved to the pin, if any.
Preferences should be prioritized first by whether their marker matches and then by the order they are stored, so that a lockfile has higher precedence than sibling forks.
Implementations§

impl Preferences
Sourcepub fn from_iter(
preferences: impl IntoIterator<Item = Preference>,
env: &ResolverEnvironment,
) -> Self
pub fn from_iter( preferences: impl IntoIterator<Item = Preference>, env: &ResolverEnvironment, ) -> Self
Create a map of pinned packages from an iterator of Preference entries.
The provided ResolverEnvironment will be used to filter the preferences
to an applicable subset.
Sourcepub fn iter(
&self,
) -> impl Iterator<Item = (&PackageName, impl Iterator<Item = (&UniversalMarker, &PreferenceIndex, &Version)>)>
pub fn iter( &self, ) -> impl Iterator<Item = (&PackageName, impl Iterator<Item = (&UniversalMarker, &PreferenceIndex, &Version)>)>
Returns an iterator over the preferences.
