Struct BitsPerFragment 

pub struct BitsPerFragment(pub u8);

BitsPerFragment represents the Huffman’s tree degree that is the power of two. It represents number of bits needed to store the degree. It can be used to construct minimum-redundancy coding whose codeword lengths are a multiple of this number of bits. It is faster than Degree and should be preferred for degrees that are the powers of two.

Trait Implementations

impl Clone for BitsPerFragment

fn clone(&self) -> BitsPerFragment

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<BitsPerFragment> for Degree

fn from(bits_per_fragment: BitsPerFragment) -> Self

Converts to this type from the input type.

impl Mul<u32> for BitsPerFragment

type Output = u32

The resulting type after applying the * operator.

fn mul(self, rhs: u32) -> Self::Output

Performs the * operation.

impl TreeDegree for BitsPerFragment

fn as_u32(&self) -> u32

Returns the degree of the Huffman tree as u32.

fn write_size_bytes(&self) -> usize

Returns number of bytes that self.write writes to the output.

fn write(&self, output: &mut dyn Write) -> Result<()>

Writes self to output.

fn read(input: &mut dyn Read) -> Result<Self>

Reads Self from input.

fn get_fragment(&self, bits: u32, fragment_nr: u32) -> u32

Returns the fragment_nr-th fragment of bits. Result is less than self.tree_degree().

fn push_front(&self, bits: &mut u32, fragment: u32)

Appends the fragment (that must be less than self.tree_degree) to the least significant digit (bits) of bits.

fn pop_front(&self, bits: &mut u32) -> u32

Removes from bits and returns its fragment stored on least significant digit (bits).

fn code_capacity(&self) -> u8

Returns the largest number of fragments that can be explicitly stored in the code. Longer codes begin with a sequence of zeros and only their last fragments are explicitly represented.

fn reverse_code(&self, bits: u32, len: u32) -> u32

impl TryFrom<Degree> for BitsPerFragment

type Error = &'static str

The type returned in the event of a conversion error.

fn try_from(value: Degree) -> Result<Self, Self::Error>

Performs the conversion.
