Greyblake Nutype by greyblake
Rust newtype with guarantees
About Greyblake Nutype
From the project's README at github.com/greyblake/nutype. Lightly cleaned for readability; for the full source see the upstream repo.
Nutype is a proc macro that allows adding extra constraints like sanitization and validation to the regular newtype pattern. The generated code makes it impossible to instantiate a value without passing the checks. It works this way even with deserialization.
