Struct PixelHash

pub struct PixelHash(/* private fields */);

Represents a 8-byte hash.

Implementations

impl PixelHash

pub fn to_signed(self) -> i64

Converts the PixelHash into a signed 64-bit integer.

This function takes the PixelHash instance and interprets it as an unsigned 64-bit integer, then converts it to a signed 64-bit integer using a bitwise XOR with a fixed value. This transformation ensures that the conversion covers the full range of a signed 64-bit integer and can be used for comparison and sorting operations.

Returns

An i64 value which represents the signed integer interpretation of the PixelHash.

pub fn from_signed(v: i64) -> Self

Converts a signed 64-bit integer back into a PixelHash.

This function interprets the signed integer as a transformed pixel hash, reversing the transformation done by to_signed. The conversion back to a PixelHash is achieved by applying a bitwise XOR with a fixed value, effectively reversing the previous transformation.

This method is useful for reconstructing a PixelHash from a signed integer representation, especially in contexts where PixelHash values are stored or sorted as signed integers.

Arguments

• v - An i64 that represents the signed integer interpretation of a pixel hash.

Returns

A PixelHash constructed from the provided signed integer.

Trait Implementations

impl Clone for PixelHash

fn clone(&self) -> PixelHash

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PixelHash

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for PixelHash

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<PixelHash> for [u8; 8]

fn from(value: PixelHash) -> Self

Converts to this type from the input type.

impl From<PixelHash> for String

Converts an Md5Hash into a hex string.

fn from(value: PixelHash) -> Self

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

Performs the conversion.

impl TryFrom<String> for PixelHash

type Error = PixelHashParseError
