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

    # File lib/prism/node.rb, line 15609
    def initialize(source, node_id, location, flags, expression, keyword_loc, rescue_expression)
      @source = source
      @node_id = node_id

      @flags = flags
      @expression = expression
      @keyword_loc = keyword_loc
      @rescue_expression = rescue_expression
    end

Initialize a new `RescueModifierNode` node.

type ()
Source

    # File lib/prism/node.rb, line 15687
    def self.type
      :rescue_modifier_node
    end

Return a symbol representation of this node type. See ‘Node::type`.

### 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.
