pub fn to_a(interp: &mut Artichoke, value: Value) -> Result<Value, Error>
Expand description

Fallible coercion of the given value to a Ruby Array via #to_a.

If the given value is a array, it is returned. If the give value responds to a #to_a method, it is called. Otherwise, a TypeError is raised.

If this function returns Ok, the returned Value is guaranteed to be a non-nil Ruby Array.


  • If the call to #to_a returns an error, that error is returned.
  • If the call to #to_a returns anything other than an Array, a TypeError is returned.
