koruma-core

Core traits and types for the koruma validation ecosystem. Most users should depend on koruma instead of this crate directly.

Use this crate when you are:

• Implementing custom validators without the proc-macro layer
• Building tooling that only needs the trait definitions

What it provides

• Validate<T>: implemented by validator structs.
• ValidationError: implemented by generated error structs.
• BuilderWithValue<T>: implemented by #[koruma::validator] builders for with_value().
• ValidateExt: used for nested/newtype validation.
• NewtypeValidation: marker for newtype structs with transparent error access.
