auto_from
This library exports the auto_from
procedural attribute macro. It is used
to automatically generate std::convert::From
implementations for enum
variants containing only one field. It currently works for tuple or struct
variants. Here is a small example:
extern crate auto_from;
use auto_from;
This should be most useful when constructing error enums that require
writing many From
implementations, or using many
.map_error(|e| MyError::Variant(e))
calls across the code. This crate
just simplifies the process.
