Trait verify::Verifier

pub trait Verifier<S: Span> {
    type Error: Error;
    fn verify_value<V: ?Sized + Validate<Span = S>>(
        &self, 
        value: &V
    ) -> Result<(), Self::Error>;

    fn verify_value_with_span<V: ?Sized + Validate<Span = S>>(
        &self, 
        value: &V, 
        _span: Option<V::Span>
    ) -> Result<(), Self::Error> { ... }
}

This trait is implemented by types that validate a value internally.

It is useful when the actual Validator is not exposed, or there might be more than one validations taking place for the same value.

Associated Types

type Error: Error
