I have managed to port my project mostly to rust 2018. However, there is one final problem.
I was using error_chain which is deprecated,
I can't import the error_chain macro anymore using the new way to import macros.
I thought about moving to the failure create but that also looks abandoned as it hasn't had a commit in the last few months.
What would people recommend ?
I have around twenty errors defined with the error_chain macro and use bail! a lot throughout mu code
I also pass around ten errors from dependencies.
Is there a recommended way to handle errors that I have missed ?
Thanks
It looks like there is a workaround for error_chain
here: Importing the macro Rust 2018 way · Issue #250 · rust-lang-deprecated/error-chain · GitHub
// Import the actual error_chain macro...
use error_chain::error_chain;
// ...and also import all the macros it uses internally
use error_chain::error_chain_processing;
use error_chain::impl_error_chain_processed;
use error_chain::impl_error_chain_kind;
use error_chain::impl_extract_backtrace;
error_chain! {
...
}
There's currently a pull request open on the error_chain
repository to fix this, so that you can just do use error_chain::error_chain
.

Also, there's a good thread here where people discussed what the most 'current' way of doing error handling is.
