Struct Environment 

pub struct Environment {
    pub do_not_track: Option<String>,
    pub ci: Option<String>,
    pub opted_out: bool,
}

The inputs decide reads: the two environment variables that matter and the local opt-out. Built through Environment::from_vars so the decision itself never touches std::env, and a test can hand it a map.

Fields

do_not_track: Option<String>

DO_NOT_TRACK, if the variable is present at all.

ci: Option<String>

CI, if the variable is present at all.

opted_out: bool

Whether the person opted out on this machine.

Implementations

impl Environment

pub fn from_vars(get: impl Fn(&str) -> Option<String>, opted_out: bool) -> Self

Builds the environment through a lookup the caller supplies — std::env::var in production, a map in a test.
