Struct ibc::core::ics24_host::identifier::ChannelId

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

Implementations

impl ChannelId

pub fn new(identifier: u64) -> Self

Builds a new channel identifier. Like client and connection identifiers, channel ids are deterministically formed from two elements: a prefix prefix, and a monotonically increasing counter, separated by a dash “-”. The prefix is currently determined statically (see ChannelId::prefix()) so this method accepts a single argument, the counter.

let chan_id = ChannelId::new(27);
assert_eq!(chan_id.to_string(), "channel-27");

pub fn prefix() -> &'static str

Returns the static prefix to be used across all channel identifiers.

pub fn as_str(&self) -> &str

Get this identifier as a borrowed &str

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

Get this identifier as a borrowed byte slice
