Implementations

impl ShapeEncoding

pub fn encode_as_shape_encoding(sampler: &Sampler) -> ShapeEncoding

pub fn encode_binary_image(image: &BinaryImage) -> ShapeEncodingString

pub fn encode_binary_image_as_hex_encoding_string_and_size( image: &BinaryImage, ) -> (ShapeEncodingString, usize)

pub fn encode_binary_image_as_shape_encoding_and_size( image: &BinaryImage, ) -> (ShapeEncoding, usize)

pub fn decode_from(shape_string: &ShapeEncodingString) -> Shape

decode shape from hexstring

pub fn bits_to_binary_image(bits: &BitVec) -> BinaryImage

pub fn bits_to_binary_image_with_limit( bits: &BitVec, limit: usize, ) -> BinaryImage

pub fn bits(&self) -> BitVec

pub fn bitstring(&self) -> ShapeEncodingString

pub fn hexstring(&self) -> ShapeEncodingString

pub fn hexstring_trim(&self) -> ShapeEncodingString

because hexstring may contain trailing 0s, trimming the last 4 bits would yield better prefix match

pub fn hexstring_to_bits(string: &str) -> BitVec

pub fn hexstring_to_bits_length(hexstring_len: usize) -> usize

pub fn bitstring_to_bits(string: &str) -> BitVec

pub fn bits_to_bitstring(bits: &BitVec) -> String

pub fn bits_to_hexstring(bits: &BitVec) -> String

pub fn pow_of_two(n: usize) -> usize

pub fn pow_of_four(n: usize) -> usize

pub fn is_pow_of_four(n: usize) -> bool

pub fn next_pow_of_four(n: usize) -> usize

pub fn layer_from_area(n: usize) -> usize

pub fn length_from_area(n: usize) -> usize

pub fn length_from_size(n: usize) -> usize

pub fn area_from_length(length: usize) -> usize

pub fn size_from_length(length: usize) -> usize

pub fn size(&self) -> usize

side of the square of the image must be power of 2

pub fn area(&self) -> usize

area of the image equals to size*size

pub fn length(&self) -> usize

length of the shape encoding guaranteed to be smaller than (not equal to) 2*size^2

pub fn shape_encoding_diff( me: &ShapeEncodingString, other: &ShapeEncodingString, ) -> u64

pub fn shape_encoding_diff_bits(a: &BitVec, b: &BitVec) -> u64

Almost like humming distance between the two bit strings, but more significant bits have higher weights

Trait Implementations

impl Default for ShapeEncoding

fn default() -> ShapeEncoding

Returns the “default value” for a type.
