Support custom guard errors #15

Closed MathiasKoch closed 3 years ago

MathiasKoch commented 3 years ago

Introduce new syntax with named keywords ["transitions", "temporary_context", "guard_error"].
Change signature of all guards to return Result<(), ..>.
Add support for custom guard errors, with a default to ().

Fixes #12

It should be straight forward for me to add some kind of naming override/prefix/postfix, now that the named syntax is introduced, in relation to #1 if you think that would be a suitable way of solving that?

Very nice! I'll give this a closer look today :)

@korken89 Fixed.. Turns out i missed a colon in the test run code :)

Could you perhaps follow the merge up with a new release to crates?
