Struct blot::seal::Seal

pub struct Seal<T: Multihash> { /* fields omitted */ }

The Seal type. See the module level documentation for more.

Methods

impl<T: Multihash> Seal<T>

pub fn digest(&self) -> &[u8]

pub fn tag(&self) -> &T

pub fn digest_hex(&self) -> String

pub fn from_str(input: &str) -> Result<Seal<T>, SealError>

Creates a Seal from a string. The string must have either the Objecthash prefix **REDACTED** or the blot SEAL_MARK.

You can use [from_bytes] if you have a list of bytes.

Examples

use blot::seal::Seal;
use blot::multihash::{Multihash, Sha2256};

let seal_classic: Result<Seal<Sha2256>, _> = Seal::from_str("**REDACTED**1220a6a6e5e783c363cd95693ec189c2682315d956869397738679b56305f2095038");
let seal: Result<Seal<Sha2256>, _> = Seal::from_str("771220a6a6e5e783c363cd95693ec189c2682315d956869397738679b56305f2095038");

assert!(seal_classic.is_ok());
assert!(seal.is_ok());
assert_eq!(seal.unwrap(), seal_classic.unwrap());

pub fn from_bytes(bytes: &[u8]) -> Result<Seal<T>, SealError>

Creates a Seal from a list of bytes. The first byte must be the SEAL_MARK.

You can use [from_str] if your redacted hash uses the original Objecthash "**REDACTED**" prefix.

Examples

use blot::seal::Seal;
use blot::multihash::{Multihash, Sha2256};
use hex::FromHex;

let bytes = Vec::from_hex("771220a6a6e5e783c363cd95693ec189c2682315d956869397738679b56305f2095038").unwrap();
let seal: Result<Seal<Sha2256>, _> = Seal::from_bytes(&bytes);

assert!(seal.is_ok());

Errors

This operation fails with SealError::NotRedacted if the first byte is not 0x77, the seal mark.
