Stellar Language Inclusion Checks

You can use Stellar language inclusion checks such as "in", "and", and "not" to define the content of the Stellar syntax.

  • in supports string contains. For example, 'foo' in 'foobar' == true

  • in supports collection contains. For example, 'foo' in [ 'foo', 'bar' ] == true

  • in supports map key contains. For example, 'foo' in { 'foo' : 5} == true

  • not in is the negation of the in expression. For example, 'grok' not in 'foobar' == true`
