Structured Validator Library for Rust

A library for validating structured data.

Description

A Validation library designed to be extendable with the use of Rust's extension trait, for example, you can bring your own i18n by implementing extension trait against LocaleData and ValidateErrorStore

Here are the examples of where Poem's i18n and Dioxus's i18n are being used.

You can also extend Name and hook in your own RegExp of your choosing, or you could use your own Post Code Validator; the possibility is endless.
