Implementations§
Source§impl PythonInstallation
impl PythonInstallation
Sourcepub fn find(
request: &PythonRequest,
environments: EnvironmentPreference,
preference: PythonPreference,
download_list: &ManagedPythonDownloadList,
cache: &Cache,
preview: Preview,
) -> Result<Self, Error>
pub fn find( request: &PythonRequest, environments: EnvironmentPreference, preference: PythonPreference, download_list: &ManagedPythonDownloadList, cache: &Cache, preview: Preview, ) -> Result<Self, Error>
Find an installed PythonInstallation.
This is the standard interface for discovering a Python installation for creating
an environment. If interested in finding an existing environment, see
[PythonEnvironment::find] instead.
Note we still require an EnvironmentPreference as this can either bypass virtual environments
or prefer them. In most cases, this should be EnvironmentPreference::OnlySystem
but if you want to allow an interpreter from a virtual environment if it satisfies the request,
then use EnvironmentPreference::Any.
See [find_installation] for implementation details.
Sourcepub fn find_best(
request: &PythonRequest,
environments: EnvironmentPreference,
preference: PythonPreference,
download_list: &ManagedPythonDownloadList,
cache: &Cache,
preview: Preview,
) -> Result<Self, Error>
pub fn find_best( request: &PythonRequest, environments: EnvironmentPreference, preference: PythonPreference, download_list: &ManagedPythonDownloadList, cache: &Cache, preview: Preview, ) -> Result<Self, Error>
Find an installed PythonInstallation that satisfies a requested version, if the request cannot
be satisfied, fallback to the best available Python installation.

Find or fetch a PythonInstallation.
Unlike PythonInstallation::find, if the required Python is not installed it will be installed automatically.

Download and install the requested installation.
