formars-core

Typed schema primitives with a dyn-safe erased view for form validation: builder-first composition (object(), string(), coerced::<T>(), ...), a Value tree with JSON interop behind the serde feature, path-addressed typed errors, and the Schema/DynSchema dual view.

use formars_core::prelude::*;

let schema = object().field("email", string().email());
assert!(schema.validate_value(&Value::from("nope")).len() == 1);

This crate is macro-free and dependency-light; formars-derive adds #[derive(FormSchema)] on top of it. See the repository and the formars facade for the full toolkit.
