Struct hawk::PayloadHasher

pub struct PayloadHasher { /* fields omitted */ }

A utility for hashing payloads. Feed your entity body to this, then pass the finish result to a request or response.

Methods

impl PayloadHasher

pub fn new<B>(content_type: B, algorithm: &'static Algorithm) -> Self where
    B: AsRef<[u8]>, 

Create a new PayloadHasher. The content_type should be lower-case and should not include parameters. The digest is assumed to be the same as the digest used for the credentials in the request.

pub fn hash<B1, B2>(
    content_type: B1,
    algorithm: &'static Algorithm,
    payload: B2
) -> Vec<u8> where
    B1: AsRef<[u8]>,
    B2: AsRef<[u8]>, 

Hash a single value and return it

pub fn update<B>(&mut self, data: B) where
    B: AsRef<[u8]>, 

Update the hash with new data.

pub fn finish(self) -> Vec<u8>

Finish hashing and return the result

Note that this appends a newline to the payload, as does the JS Hawk implementaiton.
