    // Provided method
    fn validator_info(&self) -> &'static FormPartialInfo { ... }
}

The type of a partially populated and as-yet-unvalidated form. Structs for and implementations of this trait can be generated via derive macro.

Required Associated Constants

const INFO: &'static FormPartialInfo

Required Associated Types

type Form: Form<Partial = Self>

type Validation: FormValidation<Partial = Self>

type Error: Send + 'static

Required Methods

fn form(&self) -> Result<Self::Form, &'static str>

where Self: Sized,

Converts the partial into a form.

Preconditions

• The form should already have been validated.

Errors

Only structural/type errors will be returned here, with only the name of the field to be returned.

No other validation is performed here.

fn validate<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Self::Validation, Self::Error>> + Send + 'async_trait>>

where Self: Sized + 'async_trait, 'life0: 'async_trait,

Runs all the validators on the form and calculates errors.

Should only be called once.

Errors

Returns direct errors from validators if one was thrown.

Provided Methods

fn validator_info(&self) -> &'static FormPartialInfo

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
