Function to_bytes_limited

pub async fn to_bytes_limited<B: MessageBody>(
    body: B,
    limit: usize,
) -> Result<Result<Bytes, B::Error>, BodyLimitExceeded>

Collects the bytes produced by body, up to limit bytes.

If a chunk read from poll_next causes the total number of bytes read to exceed limit, an Err(BodyLimitExceeded) is returned.

Any errors produced by the body stream are returned immediately as Ok(Err(B::Error)).

Examples

use actix_http::body::{self, to_bytes_limited};
use bytes::Bytes;

let body = body::None::new();
let bytes = to_bytes_limited(body, 10).await.unwrap().unwrap();
assert!(bytes.is_empty());

let body = Bytes::from_static(b"123");
let bytes = to_bytes_limited(body, 10).await.unwrap().unwrap();
assert_eq!(bytes, "123");

let body = Bytes::from_static(b"123");
assert!(to_bytes_limited(body, 2).await.is_err());
