Struct hex_string::HexString

pub struct HexString(_);

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.

Methods

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
