Enum Python 

pub enum Python {
    Pyenv(Pyenv),
    System(PythonExecutable),
}

A python executable, either a pyenv one or the system python (i.e. whatever else is in $PATH).

Variants

Pyenv(Pyenv)

System(PythonExecutable)

Implementations

impl Python

pub fn system( pyenv_root: Option<PyenvRoot>, ) -> Result<PythonExecutable, SystemPythonError>

Lookup the current system python, i.e., whatever next is in $PATH that’s not the current executable or a pyenv shim.

Pass a PyenvRoot to avoid pyenv shims. If there is no pyenv root than None will work.

Specifically, this returns the next python on $PATH, excluding the current executable and $PYENV_ROOT/shims/python. Otherwise, an infinite loop would be formed between ourselves and $PYENV_ROOT/shims/python.

See SystemPythonError for possible errors.

impl Python

pub fn new() -> Result<Self, PythonError>

Lookup a python executable.

If a pyenv python cannot be found (see Pyenv::new), try finding the system python (see Python::system). If neither can be found, return the errors for both in PythonError.
