Struct fletcher::Fletcher

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

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

Trait Implementations

impl<T> Default for Fletcher<T> where
    T: FletcherAccumulator, 

fn default() -> Self

Returns the “default value” for a type.
