ReadTimeout, a subclass of Timeout::Error, is raised if a chunk of the response cannot be read within the read_timeout.

WriteTimeout, a subclass of Timeout::Error, is raised if a chunk of the response cannot be written within the write_timeout. Not raised on Windows.

A compiler is a visitor that returns the value of each node as it visits. This is as opposed to a visitor which will only walk the tree. This can be useful when you are trying to compile a tree into a different format.

For example, to build a representation of the tree as s-expressions, you could write:

class SExpressions < Prism::Compiler
  def visit_arguments_node(node) = [:arguments, super]
  def visit_call_node(node) = [:call, super]
  def visit_integer_node(node) = [:integer]
  def visit_program_node(node) = [:program, super]
end

Prism.parse("1 + 2").value.accept(SExpressions.new)
# => [:program, [[[:call, [[:integer], [:arguments, [[:integer]]]]]]]]

bar(&args)
^^^^^^^^^^

Represents a block local variable.

a { |; b| }
       ^

Represents assigning to a method call.

foo.bar, = 1
^^^^^^^

begin
rescue => foo.bar
