Struct Env 

pub struct Env { /* private fields */ }

Implementations

impl Env

pub fn load(path: &Path) -> Result<Self>

Read .run/.env. A missing file is not an error: the defaults baked into docker-compose.yml still apply.

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

pub fn get_or<'a>(&'a self, key: &str, fallback: &'a str) -> &'a str

pub fn set(&mut self, key: &str, value: impl Into<String>)

pub fn is_true(&self, key: &str, fallback: bool) -> bool

pub fn truthy(value: &str) -> bool

The same spelling of yes the shell accepts, for a value read from anywhere — a file, or a running container’s environment.

pub fn iter(&self) -> impl Iterator<Item = (&String, &String)>

pub fn derive(&mut self, root: &Path)

The values the shell’s load_env computes after sourcing the file.

root is the workspace directory: the settings hold paths relative to it, and compose resolves a relative path against its own project directory, which is somewhere else entirely — so they are made absolute here or the bind mounts point at nothing.
