Function watchexec::paths::summarise_events_to_env

pub fn summarise_events_to_env<'events>(
    events: impl IntoIterator<Item = &'events Event>
) -> HashMap<&'static str, OsString>

Summarise Events as a set of environment variables by category.

• CREATED -> Create(_)
• META_CHANGED -> Modify(Metadata(_))
• REMOVED -> Remove(_)
• RENAMED -> Modify(Name(_))
• WRITTEN -> Modify(Data(_)), Access(Close(Write))
• OTHERWISE_CHANGED -> anything else
• plus COMMON with the common prefix of all paths (even if there’s only one path).

It ignores non-path events and pathed events without event kind. Multiple events are sorted in byte order and joined with the platform-specific path separator (: for unix, ; for Windows).
