timeout

Importance_2
timeout(sec, klass = nil, message = nil) public

Perform an operation in a block, raising an error if it takes longer than sec seconds to complete.

sec

Number of seconds to wait for the block to terminate. Any number may be used, including Floats to specify fractional seconds. A value of 0 or nil will execute the block without any timeout.

klass

Exception Class to raise if the block fails to terminate in sec seconds. Omitting will use the default, Timeout::Error

message

Error message to raise with Exception Class. Omitting will use the default, “execution expired”

Returns the result of the block if the block completed before sec seconds, otherwise throws an exception, based on the value of klass.

The exception thrown to terminate the given block cannot be rescued inside the block unless klass is given explicitly.

Note that this is both a method of module Timeout, so you can include Timeout into your classes so they have a #timeout method, as well as a module method, so you can call it directly as Timeout.timeout().
