impl<'a> DeferredCallClient for SipHasher24<'a>

fn handle_deferred_call(&self)

fn register(&'static self)

impl<'a> Hasher<'a, 8> for SipHasher24<'a>

fn set_client(&'a self, client: &'a dyn Client<8>)

Set the client instance which will receive hash_done() and add_data_done() callbacks. This callback is called when the data has been added to the hash engine. The callback should follow the Client add_data_done callback.

fn add_data( &self, data: SubSlice<'static, u8> ) -> Result<usize, (ErrorCode, SubSlice<'static, u8>)>

Add data to the hash block. This is the data that will be used for the hash function. Returns the number of bytes parsed on success There is no guarantee the data has been written until the add_data_done() callback is fired. On error the return value will contain a return code and the original data The possible ErrorCodes are:

fn add_mut_data( &self, data: SubSliceMut<'static, u8> ) -> Result<usize, (ErrorCode, SubSliceMut<'static, u8>)>

Add data to the hash block. This is the data that will be used for the hash function. Returns the number of bytes parsed on success There is no guarantee the data has been written until the add_data_done() callback is fired. On error the return value will contain a return code and the original data The possible ErrorCodes are:

fn run( &'a self, digest: &'static mut [u8; 8] ) -> Result<(), (ErrorCode, &'static mut [u8; 8])>

Request the implementation to generate a hash and stores the returned hash in the memory location specified. This doesn’t return any data, instead the client needs to have set a hash_done handler to determine when this is complete. On error the return value will contain a return code and the original data If there is data from the add_data() command asyncrously waiting to be written it will be written before the operation starts. The possible ErrorCodes are:

fn clear_data(&self)

Clear the internal state of the engine. This won’t clear the buffers provided to this API, that is up to the user to clear.

impl<'a> SipHash for SipHasher24<'a>

fn set_keys(&self, k0: u64, k1: u64) -> Result<(), ErrorCode>

Optionaly call before Hasher::run() to specify the keys used The possible ErrorCodes are:
