The answer of buildPath.

Type Literal

{
  ok: true;
  path: string;
}

The pattern built a path, and every part that needs a value has one.

Type Literal

{
  missing: string;
  ok: false;
  reason: "missing";
}

A part needs a value that the caller did not give.

missing names the param as the PATTERN declares it, with each hyphen kept, so a caller reports the name that its author wrote.

Type Literal

{
  ok: false;
  param: string;
  reason: "unresolvable";
  value: string;
}

A param carries a value that no path can hold, so the pattern matches the result back never. param names the param, and value holds what the caller gave.

A dot segment is the one such value today: see isDotSegment.
