Struct Env 

pub struct Env {
    pub home: PathBuf,
    pub config_dir: PathBuf,
    pub config_file: PathBuf,
    pub state_dir: PathBuf,
    pub cwd: PathBuf,
    pub session_cookie: Option<String>,
}

Where the tool reads and writes, and where it was invoked from.

Fields

home: PathBuf

The user’s home directory, used to expand a leading ~ in templates.

config_dir: PathBuf

The directory holding config.yaml and the base directory.

config_file: PathBuf

The configuration file itself. Absolute, even when --config named a relative path.

state_dir: PathBuf

Where cached answers are kept.

cwd: PathBuf

The directory the command was invoked from.

session_cookie: Option<String>

A session cookie supplied through the environment, which takes precedence over the one in the configuration file.

Implementations

impl Env

pub fn capture(config_override: Option<&Path>) -> Result<Self, EnvError>

Captures the environment, optionally overriding the configuration file.

The configuration directory is the first of: the parent of an explicit --config file, $AOC_CONFIG_DIR, $XDG_CONFIG_HOME/aoc, or ~/.config/aoc. A relative --config path is resolved against the current directory first, so both it and the directory derived from it name a real place rather than depending on where the process later looks from.

Errors

Returns EnvError if the home or current directory cannot be determined.

Trait Implementations

impl Clone for Env

fn clone(&self) -> Env

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Env

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

Formats the value using the given formatter.
