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

pub struct ChannelId(_);

Implementations

impl ChannelId

pub fn new(counter: 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 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

Trait Implementations

impl AsRef<str> for ChannelId

fn as_ref(&self) -> &str

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

impl Clone for ChannelId

fn clone(&self) -> ChannelId

Returns a copy 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

Formats the value using the given formatter.

impl Default for ChannelId

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for ChannelId

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

Deserialize this value from the given Serde deserializer.

impl Display for ChannelId

This implementation provides a to_string method.

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

Formats the value using the given formatter.

impl FromStr for ChannelId

type Err = ValidationError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl Hash for ChannelId

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, 

Feeds a slice of this type into the given Hasher.

impl Ord for ChannelId

fn cmp(&self, other: &ChannelId) -> Ordering

This method returns an Ordering between self and other.

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

Compares and returns the maximum of two values.

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

Compares and returns the minimum of two values.

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

Restrict a value to a certain interval.

impl PartialEq<ChannelId> for ChannelId

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialEq<str> for ChannelId

Equality check against string literal (satisfies &ChannelId == &str).

use core::str::FromStr;
use ibc::core::ics24_host::identifier::ChannelId;
let channel_id = ChannelId::from_str("channelId-0");
assert!(channel_id.is_ok());
channel_id.map(|id| {assert_eq!(&id, "channelId-0")});

fn eq(&self, other: &str) -> bool

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl PartialOrd<ChannelId> for ChannelId

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

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

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

This method tests less than (for self and other) and is used by the < operator.

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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

impl Serialize for ChannelId

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

Serialize this value into the given Serde serializer.
