elixir try catch
In Elixir, the try
and catch
keywords are used to handle exceptions. The try
block is used to enclose a section of code that may raise an exception, while the catch
block is used to handle the exception if it occurs.
Here is an example of how to use try
and catch
in Elixir:
try do
# Code that may raise an exception
raise "Oops, something went wrong!"
catch
# Exception handling code
exception -> IO.puts "An exception occurred: #{exception}"
end
In this example, the raise
function is used to deliberately raise an exception. If the exception is raised within the try
block, the code execution will be transferred to the catch
block. The exception
variable in the catch
block captures the raised exception, which can then be used for further processing or error handling.
It's important to note that in Elixir, exceptions are not used for flow control or error handling in the same way as in other languages. Instead, Elixir encourages the use of functional programming techniques and the with
construct for error handling and control flow.
