Struct Seal 

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

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

Implementations

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.

Trait Implementations

impl<T: Multihash> Blot for Seal<T>

fn blot<D: Multihash>(&self, _: &D) -> Harvest

fn digest<D: Multihash>(&self, digester: D) -> Hash<D>

impl<T: Clone + Multihash> Clone for Seal<T>

fn clone(&self) -> Seal<T>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<T: Debug + Multihash> Debug for Seal<T>

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

Formats the value using the given formatter.

impl<T: Multihash> From<Seal<T>> for Value<T>

fn from(raw: Seal<T>) -> Value<T>

Converts to this type from the input type.

impl<T: PartialEq + Multihash> PartialEq for Seal<T>

fn eq(&self, other: &Seal<T>) -> 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.
