Implementations§

Source§

impl HashAccumulator

Source

pub fn new() -> HashAccumulator

Source

pub fn concat(self, data: impl AsRef<[u8]>) -> HashAccumulator

Effectively concatenates data to the payload-to-be-hashed

Source

pub fn concat_mut(&mut self, data: impl AsRef<[u8]>)

Source

pub fn input_length(&self) -> usize

Source

pub fn finalize(self) -> Hash

impl Default for HashAccumulator

Source§

fn default() -> HashAccumulator

Returns the “default value” for a type. Read more

Blanket Implementations§

Source§

impl<T> Any for T
where T: 'static + ?Sized,

Source§

fn type_id(&self) -> TypeId

Gets the TypeId of self. Read more

impl<U> As for U

Source§

fn as_<T>(self) -> T
where T: CastFrom<U>,

Casts self to type T. The semantics of numeric casting with the as operator are followed, so <T as As>::as_::<U> can be used in the same way as T as U for numeric conversions. Read more

fn borrow(&self) -> &T

Immutably borrows from an owned value. Read more
