Struct TestEnv 

pub struct TestEnv { /* private fields */ }

In-memory environment + optional platform directory overrides for tests.

Build with TestEnv::new or TestEnv::with_os_vars, then chain with_*_dir helpers for platform fallbacks.

Implementations

impl TestEnv

pub fn with_config_dir(self, value: impl Into<PathBuf>) -> Self

pub fn with_data_dir(self, value: impl Into<PathBuf>) -> Self

pub fn with_cache_dir(self, value: impl Into<PathBuf>) -> Self

pub fn with_home_dir(self, value: impl Into<PathBuf>) -> Self

impl TestEnv

pub fn new(vars: HashMap<String, String>) -> Self

Create a test env from UTF-8 key/value pairs.

pub fn with_os_vars(vars: HashMap<String, OsString>) -> Self

Create a test env from raw OsString values (for non-UTF-8 path tests).

pub fn insert_os(&mut self, name: impl Into<String>, value: impl AsRef<OsStr>)

Insert or replace an env var as an OsStr.

Trait Implementations

impl EnvAccess for TestEnv

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

Look up an environment variable as an OsString (preserves non-UTF-8).

fn config_dir(&self) -> Option<PathBuf>

Platform config directory (e.g. ~/.config), before the nushell suffix.

fn data_dir(&self) -> Option<PathBuf>

Platform data directory (e.g. ~/.local/share).

fn cache_dir(&self) -> Option<PathBuf>

Platform cache directory (e.g. ~/.cache).

fn home_dir(&self) -> Option<PathBuf>

User home directory.

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

UTF-8 convenience wrapper around Self::var_os.
