Trait actix_multipart::form::FieldReader

pub trait FieldReader<'t>: Sized + Any {
    type Future: Future<Output = Result<Self, MultipartError>>;

    // Required method
    fn read_field(
        req: &'t HttpRequest,
        field: Field,
        limits: &'t mut Limits
    ) -> Self::Future;
}

Trait that data types to be used in a multipart form struct should implement.

It represents an asynchronous handler that processes a multipart field to produce Self.

Required Associated Types

type Future: Future<Output = Result<Self, MultipartError>>

Future that resolves to a Self.

Required Methods

fn read_field( req: &'t HttpRequest, field: Field, limits: &'t mut Limits ) -> Self::Future

The form will call this function to handle the field.

Object Safety

This trait is not object safe.
