    F: FnOnce() -> Cow<'static, str>, 

#[must_use] pub fn new(builder: Result<T>, key: F) -> Self

Save off a key for a context that will be added to builder.

#[must_use] pub fn value<S>(self, value: S) -> Result<T> where
    S: Into<Cow<'static, str>>, 

Finish creating context and add it to Result<T>.
