Struct guppy::graph::PackageQuery

pub struct PackageQuery<'g> { /* fields omitted */ }

A query over a package graph.

This is the entry point for iterators over IDs and dependency links, and dot graph presentation. A PackageQuery is constructed through the query_ methods on PackageGraph.

Methods

impl<'g> PackageQuery<'g>

pub fn resolve(self) -> PackageSet<'g>

Resolves this query into a set of known packages, following every link found along the way.

This is the entry point for iterators.

pub fn resolve_with(self, resolver: impl PackageResolver<'g>) -> PackageSet<'g>

Resolves this query into a set of known packages, using the provided resolver to determine which links are followed.

pub fn resolve_with_fn(
    self,
    resolver_fn: impl Fn(PackageLink<'g>) -> bool
) -> PackageSet<'g>

Resolves this query into a set of known packages, using the provided resolver function to determine which links are followed.
