Struct Id20 

pub struct Id20(pub [u8; 20]);

20-byte identifier used for SHA1 info-hashes and peer IDs.

Tuple Fields

0: [u8; 20]

Implementations

impl Id20

pub const ZERO: Self

All zeros.

pub fn from_hex(s: &str) -> Result<Self, Error>

Create from a hex string (40 chars).

Errors

Returns an error if the string is not valid hex or has the wrong length.

pub fn from_base32(s: &str) -> Result<Self, Error>

Create from a base32 string (32 chars, used in magnet links).

Errors

Returns an error if the string is not valid base32 or has the wrong length.

pub fn from_bytes(bytes: &[u8]) -> Result<Self, Error>

Create from a byte slice, validating length.

Errors

Returns an error if the byte slice is not exactly 20 bytes.

pub fn to_hex(&self) -> String

Encode as lowercase hex string.

pub fn to_base32(&self) -> String

Encode as base32 string (no padding), used in magnet links.

pub fn xor_distance(&self, other: &Self) -> Self

XOR distance to another Id20 (used in DHT/Kademlia).

pub fn as_bytes(&self) -> &[u8; 20]

Return the raw bytes.

Trait Implementations

impl AsRef<[u8]> for Id20

fn as_ref(&self) -> &[u8]

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Id20

fn clone(&self) -> Id20

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Id20

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Id20

fn deserialize<D: Deserializer<'de>>(deserializer: D) -> Result<Self, D::Error>

Deserialize this value from the given Serde deserializer.

impl Display for Id20

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

Formats the value using the given formatter.

impl From<[u8; 20]> for Id20

fn from(arr: [u8; 20]) -> Self

Converts to this type from the input type.

impl Hash for Id20

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

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 Ord for Id20

fn cmp(&self, other: &Id20) -> 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.

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

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for Id20

fn eq(&self, other: &Id20) -> 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.

impl PartialOrd for Id20

fn partial_cmp(&self, other: &Id20) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for Id20

fn serialize<S: Serializer>(&self, serializer: S) -> Result<S::Ok, S::Error>

Serialize this value into the given Serde serializer.

impl Copy for Id20

impl Eq for Id20
