Trait actix_multipart::form::MultipartCollect

pub trait MultipartCollect: Sized {
    // Required methods
    fn limit(field_name: &str) -> Option<usize>;
    fn handle_field<'t>(
        req: &'t HttpRequest,
        field: Field,
        limits: &'t mut Limits,
        state: &'t mut State
    ) -> LocalBoxFuture<'t, Result<(), MultipartError>>;
    fn from_state(state: State) -> Result<Self, MultipartError>;
}

Trait that allows a type to be used in the MultipartForm extractor.

You should use the MultipartForm macro to derive this for your struct.

Required Methods

fn limit(field_name: &str) -> Option<usize>

An optional limit in bytes to be applied a given field name. Note this limit will be shared across all fields sharing the same name.

fn handle_field<'t>( req: &'t HttpRequest, field: Field, limits: &'t mut Limits, state: &'t mut State ) -> LocalBoxFuture<'t, Result<(), MultipartError>>

The extractor will call this function for each incoming field, the state can be updated with the processed field data.

fn from_state(state: State) -> Result<Self, MultipartError>

Once all the fields have been processed and stored in the state, this is called to convert into the struct representation.

Object Safety

This trait is not object safe.
