Struct Multipart
pub struct Multipart {
inner: Multipart<'static>,
}
Expand description
Extractor that parses multipart/form-data
requests (commonly used with file uploads).
โ ๏ธ Since extracting multipart form data from the request requires consuming the body, the
Multipart
extractor must be last if there are multiple extractors in a handler.
See โthe order of extractorsโ
ยงExample
use axum::{
extract::Multipart,
routing::post,
Router,
};
use futures_util::stream::StreamExt;
async fn upload(mut multipart: Multipart) {
while let Some(mut field) = multipart.next_field().await.unwrap() {
let name = field.name().unwrap().to_string();
let data = field.bytes().await.unwrap();
println!("Length of `{}` is {} bytes", name, data.len());
}
}
let app = Router::new().route("/upload", post(upload));
ยงLarge Files
For security reasons, by default, Multipart
limits the request body size to 2MB.
See DefaultBodyLimit
for how to configure this limit.

Implementationsยง
ยงimpl Multipart
impl Multipart
pub async fn next_field(&mut self) -> Result<Option<Field<'_>>, MultipartError>
pub async fn next_field(&mut self) -> Result<Option<Field<'_>>, MultipartError>
Yields the next Field
if available.
Trait Implementationsยง
ยงimpl<S> FromRequest<S> for Multipart
impl<S> FromRequest<S> for Multipart
ยงtype Rejection = MultipartRejection
type Rejection = MultipartRejection
If the extractor fails itโll use this โrejectionโ type. A rejection is
a kind of error that can be converted into a response.
ยงasync fn from_request(
req: Request<Body>,
_state: &S,
) -> Result<Multipart, <Multipart as FromRequest<S>>::Rejection>
async fn from_request( req: Request<Body>, _state: &S, ) -> Result<Multipart, <Multipart as FromRequest<S>>::Rejection>
Perform the extraction.
