Struct TopicId 

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

Identified of a network stream topic.

When two connected peers open a stream with the same topic id, they can communicate over it with each other.

Implementations

impl TopicId

pub const SIZE: usize = 32

pub fn generate<R>(rng: &mut R) -> TopicId

where R: Rng,

Generates random topic id using the provided RNG.

pub fn random() -> TopicId

Generates random topic id using rand::thread_rng().

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

pub fn from_slice_lossy(slice: &[u8]) -> TopicId

Creates topic id from the given byte slice. If the slice is longer than Self::SIZE, it’s truncated. If it’s shorter, it’s filled in with zeroes.

Trait Implementations

impl Clone for TopicId

fn clone(&self) -> TopicId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TopicId

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TopicId

fn deserialize<__D>( __deserializer: __D, ) -> Result<TopicId, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<[u8; 32]> for TopicId

fn from(array: [u8; 32]) -> TopicId

Converts to this type from the input type.

impl Hash for TopicId

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 PartialEq for TopicId

fn eq(&self, other: &TopicId) -> 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 Serialize for TopicId

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
