Struct Ctx 

pub struct Ctx {
    pub home: PathBuf,
    pub cwd: PathBuf,
    pub env: BTreeMap<String, String>,
    pub path: Vec<PathBuf>,
}

The slice of the process environment that profiles read: home and working directories, environment variables, and the PATH search list. Tests build one by hand so nothing depends on the real machine.

Fields

home: PathBuf

cwd: PathBuf

env: BTreeMap<String, String>

path: Vec<PathBuf>

Implementations

impl Ctx

pub fn from_process() -> Ctx

pub fn at(root: &Path) -> Ctx

The process context with cwd set to a project directory (where the manifest lives), so project-relative paths resolve there and not in a subdirectory.

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

A non-empty environment variable.

pub fn expand(&self, template: &str, root: Option<&Path>) -> PathBuf

Expand ~, {root}, {home} and relative (project) paths.

pub fn which(&self, name: &str) -> Option<PathBuf>

Resolve a binary name on PATH.
