class Prism::RescueNode
Represents a rescue statement.
begin rescue Foo, *splat, Bar => ex foo ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ end
‘Foo, *splat, Bar` are in the `exceptions` field. `ex` is in the `exception` field.
Attributes
attr_reader consequent: RescueNode

Public Class Methods
Initialize a new RescueNode
node.

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

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