Prerequisites.
Verification Version: Ruby2.6.1
Summary
We can do it.
Validation Methods
raise raises the error, rescue catches the error, in which it raises the error again, and rescue catches it
def method
p 'init'
begin
raise "first error"
rescue
P "FIRST RESCUE"
begin
raise 'second error'
rescue
P 'SECOND RESCUE'
end
end
end
execution result
> method
"init,"
"FIRST RESCUE,"
"SECOND RESCUE"
There's also a way to write a RESCUE one step out of the block without writing a BEGIN like this
def method2
p 'init'
raise "first error"
rescue
P "FIRST RESCUE"
begin
raise 'second error'
rescue
P 'SECOND RESCUE'
end
end
execution result
> method2
"init,"
"FIRST RESCUE,"
"SECOND RESCUE"
