Struct rocket::form::DataField

source ·
pub struct DataField<'r, 'i> {
    pub name: NameView<'r>,
    pub file_name: Option<&'r FileName>,
    pub content_type: ContentType,
    pub request: &'r Request<'i>,
    pub data: Data<'r>,

Expand description

A multipart form field with an underlying data stream.

Rocket preprocesses all form fields into either ValueFields or DataFields. Multipart form fields with a Content-Type are preprocessed as a DataField. The underlying data is not read into memory, but instead, streamable from the contained Data structure.

Fields§

§name: NameView<'r>

The (decoded) name of the form field.

§file_name: Option<&'r FileName>

The form fields’s file name.

§content_type: ContentType

The form field’s Content-Type, as submitted, which may or may not reflect on data.

§request: &'r Request<'i>

The request in which the form field was submitted.

§data: Data<'r>

The raw data stream.

Implementations§

source§

impl<'v> DataField<'v, '_>

source

pub fn shift(self) -> Self

Shift the name of self and return self with the shifted name.

This is identical to ValueField::shift() but for DataFields. See NameView::shift() for the details on name “shifting”.

§Example
use rocket::form::DataField;

fn push_data(field: DataField<'_, '_>) {
    let shifted = field.shift();
}
source

pub fn unexpected(&self) -> Error<'v>

Creates a complete unexpected data field Error from self.

The error will have the following properties:

§Example
use rocket::form::DataField;

fn push_data(field: DataField<'_, '_>) {
    let error = field.unexpected();
}
