pub struct ResolverOutput { /* private fields */ }Expand description
The output of a successful resolution.
Includes a complete resolution graph in which every node represents a pinned package and every edge represents a dependency between two pinned packages.
Implementations§
Source§impl ResolverOutput
impl ResolverOutput
Sourcepub fn contains(&self, name: &PackageName) -> bool
pub fn contains(&self, name: &PackageName) -> bool
Returns true if the graph contains the given package.
Sourcepub fn diagnostics(&self) -> &[ResolutionDiagnostic]
pub fn diagnostics(&self) -> &[ResolutionDiagnostic]
Return the ResolutionDiagnostics that were encountered while building the graph.
Sourcepub fn marker_tree(
&self,
index: &InMemoryIndex,
marker_env: &MarkerEnvironment,
) -> Result<MarkerTree, Box<ParsedUrlError>>
pub fn marker_tree( &self, index: &InMemoryIndex, marker_env: &MarkerEnvironment, ) -> Result<MarkerTree, Box<ParsedUrlError>>
Return the marker tree specific to this resolution.
This accepts an in-memory-index and marker environment, all of which should be the same values given to the resolver that produced this graph.
The marker tree returned corresponds to an expression that, when true, this resolution is guaranteed to be correct. Note though that it’s possible for resolution to be correct even if the returned marker expression is false.
For example, if the root package has a dependency foo; sys_platform == "macos" and resolution was performed on Linux, then the marker tree
returned will contain a sys_platform == "linux" expression. This
means that whenever the marker expression evaluates to true (i.e., the
current platform is Linux), then the resolution here is correct. But
it is possible that the resolution is also correct on other platforms
that aren’t macOS, such as Windows. (It is unclear at time of writing
whether this is fundamentally impossible to compute, or just impossible
to compute in some cases.)

impl Debug for ResolverOutput
Source§impl From<ResolverOutput> for Resolution
Convert a ResolverOutput into a uv_distribution_types::Resolution.
impl From<ResolverOutput> for Resolution
Convert a ResolverOutput into a uv_distribution_types::Resolution.
This involves converting [ResolutionGraphNode]s into Nodes, which in turn involves
dropping any extras and dependency groups from the graph nodes. Instead, each package is
collapsed into a single node, with extras and dependency groups annotating the edges, rather
than being represented as separate nodes. This is a more natural representation, but a further
departure from the PubGrub model.
For simplicity, this transformation makes the assumption that the resolution only applies to a subset of markers, i.e., it shouldn’t be called on universal resolutions, and expects only a single version of each package to be present in the graph.
