Struct PythonMinorVersionLink 

pub struct PythonMinorVersionLink {
    pub symlink_directory: PathBuf,
    pub symlink_executable: PathBuf,
    pub target_directory: PathBuf,
}

A representation of a minor version symlink directory (or junction on Windows) linking to the home directory of a Python installation.

Fields

symlink_directory: PathBuf

The symlink directory (or junction on Windows).

symlink_executable: PathBuf

The full path to the executable including the symlink directory (or junction on Windows).

target_directory: PathBuf

The target directory for the symlink. This is the home directory for a Python installation.

Implementations

impl PythonMinorVersionLink

pub fn from_installation( installation: &ManagedPythonInstallation, ) -> Option<Self>

pub fn create_directory(&self) -> Result<(), Error>

pub fn exists(&self) -> bool

Check if the minor version link exists and points to the expected target directory.

This verifies both that the symlink/junction exists AND that it points to the target_directory specified in this struct. This is important because the link may exist but point to a different installation (e.g., after an upgrade), in which case we should not use the link for the current installation.

pub fn read_target(&self) -> Option<PathBuf>

Read the target of the minor version link.

On Unix, this reads the symlink target. On Windows, this reads the junction target using the junction crate which properly handles the \??\ prefix that Windows uses internally for junction targets.

Trait Implementations

impl Clone for PythonMinorVersionLink

fn clone(&self) -> PythonMinorVersionLink

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PythonMinorVersionLink

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
