0.5.1

Version 0.5.0 introduced breaking changes:

Hash Value Type Change: The crate no longer uses String for hash values. Instead, a custom Hash struct is implemented:

#[derive(Serialize, Deserialize, Debug, Clone, PartialEq, Eq)]
pub struct Hash([u8; 32]);

impl Hash {
    pub const fn new(bytes: [u8; 32]) -> Self {
        Hash(bytes)
    }

    pub fn from_hex(hex: &str) -> Result<Self, hex::FromHexError> {
        let bytes = hex::decode(hex)?;
        if bytes.len() != 32 {
            return Err(hex::FromHexError::InvalidStringLength);
        }
        let mut array = [0u8; 32];
        array.copy_from_slice(&bytes);
        Ok(Hash(array))
    }

    pub fn to_hex(&self) -> String {
        hex::encode(self.0)
    }
}

impl AsRef<[u8]> for Hash {
    fn as_ref(&self) -> &[u8] {
        &self.0
    }
}

impl std::fmt::Display for Hash {
    fn fmt(&self, f: &mut std::fmt::Formatter<'_>) -> std::fmt::Result {
        write!(f, "{}", self.to_hex())
    }
}
