Is there a way to write do notation for a monad in a function which the return type isn't of said monad?
Since I'm fairly new to Rust, I need guidance on how error handling is done idiomatically. I find the error-handling boilerplate really annoying.
I wonder why read "1" :: Maybe Int will type check and throw an exception in runtime. Is it possible that read can ever return a Maybe a? That is what Text.Read.readMaybe is supposed to do.
any better way to this then case matching What you here bascially show is the use of a Maybe monad, so we can write it like:
Maybe expresses computations that might not produce a result due to an error. Therefore such computations must be short circuited.
I'm confused about why the two functions below involving Nothing are different:The first one has type:
