Struct HexString

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

HexString provides a structured representation of a hex string. It is guaranteed to be a valid string, whether initialized from a string or from a byte vector.

Implementations

impl HexString

pub fn from_string(s: &str) -> Result<HexString, HexStringError>

Initialize a HexString from an actual hex string. The input string must be of an even length (since it takes two hex characters to represent a byte) and must contain only characters in the range 0-9 and a-f.

This will return an InvalidStringLength error if the length is not even, and InvalidCharacter if any non-hex character is detected.

pub fn from_bytes(v: &Vec<u8>) -> HexString

Initialize a hex strign from a binary vector. This function cannot fail.

pub fn as_string(&self) -> String

Return a String representation

pub fn as_bytes(&self) -> Vec<u8>

Return a byte representation

Trait Implementations

impl Clone for HexString

fn clone(&self) -> HexString

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for HexString

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

Formats the value using the given formatter.

impl PartialEq for HexString

fn eq(&self, other: &HexString) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
