pub struct Planner<'a> { /* private fields */ }Expand description
A planner to generate an Plan based on a set of requirements.
Implementations§

impl<'a> Planner<'a>
Sourcepub fn new(resolution: &'a Resolution) -> Self
pub fn new(resolution: &'a Resolution) -> Self
Set the requirements use in the Plan.

self,
site_packages: SitePackages,
installation: InstallationStrategy,

build_options: &BuildOptions,

pub fn build( self, site_packages: SitePackages, installation: InstallationStrategy, reinstall: &Reinstall, build_options: &BuildOptions, hasher: &HashStrategy, index_locations: &IndexLocations, config_settings: &ConfigSettings, config_settings_package: &PackageConfigSettings, extra_build_requires: &ExtraBuildRequires, extra_build_variables: &ExtraBuildVariables, cache: &Cache, venv: &PythonEnvironment, tags: &Tags, ) -> Result<Plan>
Partition a set of requirements into those that should be linked from the cache, those that need to be downloaded, and those that should be removed.
The install plan will respect cache [Freshness]. Specifically, if refresh is enabled, the
plan will respect cache entries created after the current time (as per the [Refresh]
policy). Otherwise, entries will be ignored. The downstream distribution database may still
read those entries from the cache after revalidating them.
The install plan will also respect the required hashes, such that it will never return a cached distribution that does not match the required hash. Like pip, though, it will return an installed distribution that does not match the required hash.
