Struct arcode::util::range::Range

pub struct Range { /* fields omitted */ }

Methods

impl Range

pub fn new(precision: u64) -> Self

pub fn in_bottom_half(&self) -> bool

pub fn in_upper_half(&self) -> bool

pub fn in_middle_half(&self) -> bool

pub fn in_bottom_quarter(&self) -> bool

pub fn scale_upper_half(&mut self)

scaling the upper half is a left shift, to avoid overflow we minus a 1/2 first

pub fn scale_middle_half(&mut self)

subtract a quarter is the same as shifting out the second most significant bit

pub fn scale_bottom_half(&mut self)

scaling the bottom half in a left shift

pub fn calculate_range(
    &self,
    symbol: u32,
    source_model: &SourceModel
) -> (u64, u64)

returns (low, high)

pub fn update_range(&mut self, low_high: (u64, u64))

pub fn get_half(&self) -> u64

pub fn get_quarter(&self) -> u64
