Struct#eql?

(untyped other) -> bool

eql?(other) → true or false

static VALUE
rb_struct_eql(VALUE s, VALUE s2)
{
    if (s == s2) return Qtrue;
    if (!RB_TYPE_P(s2, T_STRUCT)) return Qfalse;
    if (rb_obj_class(s) != rb_obj_class(s2)) return Qfalse;
    if (RSTRUCT_LEN(s) != RSTRUCT_LEN(s2)) {
        rb_bug("inconsistent struct"); /* should never happen */
    }

    return rb_exec_recursive_paired(recursive_eql, s, s2, s2);
}

Returns true if and only if the following are true; otherwise returns false:

other.class == self.class.

For each member name name, other.name.eql?(self.name).

Example

Customer = Struct.new(:name, :address, :zip)
joe    = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
joe_jr = Customer.new("Joe Smith", "123 Maple, Anytown NC", 12345)
joe_jr.eql?(joe) # => true
joe_jr[:name] = 'Joe Smith, Jr.'
joe_jr.eql?(joe) # => false
