new (source, node_id, location, flags, expression, keyword_loc, rescue_expression)

Source

# File lib/prism/node.rb, line 15609

  @source = source
  @node_id = node_id

Public Instance Methods

=== (other)

Source

# File lib/prism/node.rb, line 15693
def ===(other)
  other.is_a?(RescueModifierNode) &&
    (expression === other.expression) &&
    (keyword_loc.nil? == other.keyword_loc.nil?) &&
    (rescue_expression === other.rescue_expression)
end

Implements case-equality for the node. This is effectively == but without comparing the value of locations. Locations are checked only for presence.
