An abstract model to produce probability ranges Can be a table, a mix of tables, or just a smart function.

Required methods

fn get_range(&self, value: V) -> (Border, Border)

Get the probability range of a value

fn find_value(&self, offset: Border) -> (V, Border, Border)

Find the value by a given probability offset, return with the range

fn get_denominator(&self) -> Border

Get the sum of all probabilities

Provided methods

fn encode(&self, value: V, re: &mut RangeEncoder, out: &mut [Symbol]) -> usize

Encode a value using a range encoder return the number of symbols written

fn decode(&self, code: Border, re: &mut RangeEncoder) -> (V, usize)

Decode a value using given 'code' on the range encoder return a (value, num_symbols_to_shift) pair
