Expand description
The process environment, as the lookup this crate’s resolvers take.
Region::from_env,
FileNameStore::default_location and the
other resolvers take a &dyn Fn(&str) -> Option<String> rather than reading std::env
themselves, so a caller (and a test) decides where the variables come from. process is
that lookup in production. It lives here once so the CLI and both bindings pass the same
function: a driving adapter never reads the environment itself, and its clippy.toml bans
std::env::var to keep it that way. The adapters’ clippy.toml bans calling process
by name too, since that’s the same read with a different path. Each adapter hands it to a
resolver at the one place it composes them, under a listed #[expect].
