Struct GroupCode 

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

Group identifier for isolating P2P networks.

GroupCode is a 16-byte identifier that creates isolated P2P networks. Peers with different group codes cannot communicate with each other.

Examples

use rustp2p::GroupCode;
use std::convert::TryFrom;

// Create from string
let group = GroupCode::try_from("my-group").unwrap();

// Create from u128
let group: GroupCode = 12345u128.into();

// Create unspecified (default)
let unspec = GroupCode::unspecified();
assert!(unspec.is_unspecified());

Implementations

impl GroupCode

pub fn unspecified() -> GroupCode

Returns an unspecified GroupCode (all zeros).

Examples

use rustp2p::GroupCode;

let unspec = GroupCode::unspecified();
assert!(unspec.is_unspecified());

pub fn is_unspecified(&self) -> bool

Checks if this GroupCode is unspecified (all zeros).

Examples

use rustp2p::GroupCode;

let unspec = GroupCode::unspecified();
assert!(unspec.is_unspecified());

Trait Implementations

impl AsRef<[u8]> for GroupCode

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

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

impl Clone for GroupCode

fn clone(&self) -> GroupCode

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GroupCode

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

Formats the value using the given formatter.

impl Default for GroupCode

fn default() -> Self

Returns the “default value” for a type.

impl From<[u8; 16]> for GroupCode

fn from(value: [u8; 16]) -> Self

Converts to this type from the input type.

impl From<i128> for GroupCode

fn from(value: i128) -> Self

Converts to this type from the input type.

impl From<u128> for GroupCode

fn from(value: u128) -> Self

Converts to this type from the input type.

impl Hash for GroupCode

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 GroupCode

fn cmp(&self, other: &GroupCode) -> 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 GroupCode

fn eq(&self, other: &GroupCode) -> 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 GroupCode

fn partial_cmp(&self, other: &GroupCode) -> 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.

fn try_from(value: &[u8]) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&String> for GroupCode

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: &String) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<&str> for GroupCode

type Error = Error

fn try_from(value: &str) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<String> for GroupCode

type Error = Error

The type returned in the event of a conversion error.

fn try_from(value: String) -> Result<Self, Self::Error>

Performs the conversion.
