> You may not like Go's convention (indeed, I don't love it although I think it works fine in practice), but the only error handling mechanism in Go is `if err != nil { ... }`. On the other hand Rust has many. This is not incompatible with your observation of "a standardized Result type". Here is a survey of the error handling landscape circa 2019: https://blog.yoshuawuyts.com/error-handling-survey/
By this definition, Go has many too. Go has lots of libraries to wrap error types, combine errors, preserve error data, etcetc.
Errors are one of the more similar things between Rust and Go, honestly.
