safe

try to execute an action an report any issue

Attempt to execute a safe action including finalizers

get a resource A and use it. Call the release function whether an exception is thrown or not when using the resource

NOTE: Eff interpreters are independent so if there is an effect short-circuiting all computations inside 'use', like Option or Either then the release function will not be called. If you want to make sure that the release function is always called "at the end of the world and whatever happens" you need to call Eff.bracketLast

evaluate first action possibly having error effects

Execute a second action if the first one is not successful, based on the error

run a safe effect but drop the finalizer errors

ignore one possible exception that could be thrown

evaluate first action possibly having exceptions

Execute a second action if the first one is not successful

evaluate first action possibly having error effects

Execute a second action if the first one is not successful and second is defined for the error

Run a safe effect

Collect finalizer exceptions if any

Memoize safe effects using a cache

if this method is called with the same key the previous value will be returned

evaluate first action possibly having error effects execute a second action whether the first is successful or not but keep track of finalizer exceptions

evaluate first action possibly throwing exceptions

Execute a second action if the first one is not successful, based on the exception

The final value type is the same as the original type
