Function join_path_syms

Source 
pub fn join_path_syms(
    path: impl IntoIterator<Item = impl Borrow<Symbol>>,
) -> String
Expand description

Joins multiple symbols with “::” into a path, e.g. “a::b::c”. If the first segment is kw::PathRoot it will be printed as empty, e.g. “::b::c”.

The generics on the path argument mean it can accept many forms, such as:

  • &[Symbol]
  • Vec<Symbol>
  • Vec<&Symbol>
  • impl Iterator<Item = Symbol>
  • impl Iterator<Item = &Symbol>

Panics if path is empty or a segment after the first is kw::PathRoot.
