Struct ChannelId 

pub struct ChannelId { /* private fields */ }

A channel identifier: name + cached canonical hash.

Implementations

impl ChannelId

pub fn new(name: ChannelName) -> ChannelId

Create a new channel ID.

pub fn parse(name: &str) -> Result<ChannelId, ChannelError>

Create from a raw name string.

pub fn name(&self) -> &ChannelName

Get the channel name.

pub fn hash(&self) -> u64

Get the cached canonical ChannelHash (32-bit).

Used as the substrate-wide key for auth, storage, and config.

pub fn wire_hash(&self) -> u16

Get the wire u16 hash for stamping the NetHeader fast-path.

Derived from the canonical hash by truncation; the wire u16 is a fast-path filter hint that may collide, while ChannelId::hash (canonical u32) is the ACL/storage key.

Trait Implementations

impl Clone for ChannelId

fn clone(&self) -> ChannelId

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ChannelId

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

Formats the value using the given formatter.

impl Display for ChannelId

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

Formats the value using the given formatter.

impl Eq for ChannelId

impl Hash for ChannelId

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 ChannelId

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