Struct Fletcher

pub struct Fletcher<T>
where
    T: FletcherAccumulator,
{ /* private fields */ }

Type to hold the state for calculating a fletcher checksum.

This is useful if you want to calculate the checksum over several small chunks of data. If you have an entire block of data the functions calc_fletcher16, calc_fletcher32, calc_fletcher64 simplify the process.

Implementations

impl<T> Fletcher<T>

where T: FletcherAccumulator,

pub fn new() -> Fletcher<T>

Construct a new checksum object using the default initial value

pub fn with_initial_values( a: <T as FletcherAccumulator>::InputType, b: <T as FletcherAccumulator>::InputType, ) -> Fletcher<T>

Construct a new checksum object with a specific set of initial values

pub fn update(&mut self, data: &[<T as FletcherAccumulator>::InputType])

Updates the checksum with the given input data

pub fn value(&self) -> T

Returns the current checksum value
