`error-stack-macros2` 0.2.0

error-stack-macros2 v0.2.0

We have a new development version of error-stack-macros2!

Fixes

This version (0.2.0) adds support for generics and external attributes to the impl_error_stack macro.

This means that types like this:

use error_stack_macros2::Error;

#[derive(Debug, Error)]
#[display("failed to retrieve credit card")]
enum CreditCardError<T>
where
	T: Display
{
	InvalidInput(T),
	Other
}

#[derive(Debug, Error)]
#[display("invalid card string")]
#[allow(non_camel_case_types)]
struct parseCardError;

...can now compile properly.

Performance

The entire source code has been refactored to eliminate unnecessary allocations, cloning, and double iterator consumptions. This should make compile times faster and reduce memory usage.

Dependencies

As promised, all dependencies have been updated to their latest versions, which in this case means performance improvements and bug fixes.
