Re: [PATCH v4 04/22] rust: validate: add `Validate` trait

[sashiko-bot@kernel.org]

> From: Benno Lossin <benno.lossin@proton.me>
> 
> Introduce the `Validate<Input>` trait and functions to validate
> `Untrusted<T>` using said trait. This allows one to access the inner
> value of `Untrusted<T>` via `validate{,_ref,_mut}` functions which

> The `Validate` trait is the only entry point for validation code, making

> The reason for restricting the types that can be inputs to

> on `Untrusted`. This is also the reason for the suggestions in the
> `Usage in API Design` section in the commit that introduced
> `Untrusted<T>`.
> 
> The `Validate::validate()` function allows additional context to be
> passed, which can be used as part of the validation process. For example
> comparing data against already negotiated information.
