pub struct RadixBits { /* private fields */ }

Expand description

The number of radix bits per pass.

Implementations

source

impl RadixBits

source

pub fn new(
 first_bits: Option<u32>,
 second_bits: Option<u32>,
 third_bits: Option<u32>
) -> Self

Returns a new RadixBits object

source

pub fn radix_bits(&self) -> u32

Total number of radix bits.

source

pub fn fanout(&self) -> u32

Total fanout.

source

pub fn pass_radix_bits(&self, pass: RadixPass) -> Option<u32>

Number of radix bits per pass.

source

pub fn pass_fanout(&self, pass: RadixPass) -> Option<u32>

Fanout per pass.

source

pub fn pass_ignore_bits(&self, pass: RadixPass) -> u32

Number of radix bits by all earlier passes.

For example, the first pass has 6 radix bits and the second pass has 6 radix bits. Then pass_ignore_bits(First) equals 0, and pass_ignore_bits(Second) equals 6.
