Struct iroh_blobs::Hash

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

Hash type used throughout.

Implementations

impl Hash

pub const EMPTY: Hash = _

The hash for the empty byte range (b"").

pub fn new(buf: impl AsRef<[u8]>) -> Hash

Calculate the hash of the provided bytes.

pub fn as_bytes(&self) -> &[u8; 32]

Bytes of the hash.

pub const fn from_bytes(bytes: [u8; 32]) -> Hash

Create a Hash from its raw bytes representation.

pub fn to_hex(&self) -> String

Convert the hash to a hex string.

pub fn fmt_short(&self) -> String

Convert to a base32 string limited to the first 10 bytes for a friendly string representation of the hash.

type Err = HexOrBase32ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Hash, <Hash as FromStr>::Err>

Parses a string s to return a value of this type.

impl Hash for Hash

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Key for Hash

fn compare(data1: &[u8], data2: &[u8]) -> Ordering

Compare data1 with data2

impl MaxSize for Hash

const POSTCARD_MAX_SIZE: usize = 32usize

The maximum possible size that the serialization of this type can have, in bytes.

impl Ord for Hash

fn cmp(&self, other: &Hash) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

impl PartialEq for Hash

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.

impl Value for Hash

type SelfType<'a> = Hash
