Struct Environment 

pub struct Environment { /* private fields */ }

A home directory and the environment variables that relocate tools.

Implementations

impl Environment

pub fn new(home: impl Into<PathBuf>) -> Self

An environment with the given home and no variables set.

pub fn with_var( self, name: impl Into<String>, value: impl Into<OsString>, ) -> Self

The same environment with one variable set.

pub fn from_process() -> Option<Self>

The environment of the running process.

Returns None when no home directory can be found, because every target lives below it and guessing one would write somewhere unknown.

pub fn home(&self) -> &Path

The home directory.

pub fn var(&self, name: &str) -> Option<&OsString>

A variable, when it is set to something other than the empty string.

An empty value is treated as unset, as most tools do: CLAUDE_CONFIG_DIR= does not move anything to the current directory.

Trait Implementations

impl Clone for Environment

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Environment

Names only: the process environment holds tokens and passwords, and a program that logs its environment must not log those.

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

Formats the value using the given formatter.

impl Eq for Environment

impl PartialEq for Environment

fn eq(&self, other: &Self) -> bool

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
