Function starlark::values::display::display_container

pub fn display_container<T: Display, Iter: ExactSizeIterator<Item = T>>(
    f: &mut Formatter<'_>, 
    prefix: &str, 
    suffix: &str, 
    items: Iter
) -> Result

Helper for display implementation of starlark container-y types.

For “normal” display, produces output like (with prefix="prefix[", suffix="]"):

prefix[] prefix[1] prefix[1, 2]

For “alternate” display, produces output like:

prefix[] prefix[ 1 ]

prefix[
  1,
  2
]

This doesn’t propagate the flags on the Formatter other than alternate.
