Trait digest_headers::prelude::AsDigest [−] [src]

pub trait AsDigest: Sized {
    type Error;
    fn as_digest(self, sha_size: ShaSize) -> Result<(Self, Digest), Self::Error>;
}

The AsDigest trait provides a method to retrieve a Digest from a given type.

Associated Types

The Error type defines any error that may occur in the creation of the Digest.

Required Methods

Retrieve a Digest from a given type, returning Self and the Digest.

An Example with Hyper

let uri = "http://example.com".parse().unwrap();
let json = r#"{"Library":"Hyper"}"#;

let mut req: Request<Body> = Request::new(Method::Post, uri);
req.set_body(json);

let (mut req, digest) = req.as_digest(ShaSize::TwoFiftySix)?;

req.headers_mut().set(DigestHeader(digest));

Implementations on Foreign Types

impl AsDigest for Request<Body>
[src]

[src]

We need to consume the body Stream in order to access it, but we can set the body again after we've concatenated the whole body together, since getting a Digest is non-destructive.

Do not call this method from the context of an asyncronous executor unless you are certain that the body in the Request is a single item. It will block waiting for all items.
