Instance methods

<=>(rhs : self) : Int32

The comparison operator.

Returns -1, 0 or 1 depending on whether self precedes rhs, equals to rhs or comes after rhs. The comparison is done based on chain identifier.

chains = Structure.read(&quot;peptide.pdb&quot;).chains

chains[0] &lt;=&gt; chains[1] # =&gt; -1
chains[1] &lt;=&gt; chains[1] # =&gt; 0
chains[2] &lt;=&gt; chains[1] # =&gt; 1
