Struct emulated_integration_tests_common::impls::HrmpChannelId

pub struct HrmpChannelId {
    pub sender: Id,
    pub recipient: Id,
}

A type that uniquely identifies an HRMP channel. An HRMP channel is established between two paras. In text, we use the notation (A, B) to specify a channel between A and B. The channels are unidirectional, meaning that (A, B) and (B, A) refer to different channels. The convention is that we use the first item tuple for the sender and the second for the recipient. Only one channel is allowed between two participants in one direction, i.e. there cannot be 2 different channels identified by (A, B). A channel with the same para id in sender and recipient is invalid. That is, however, not enforced.

Fields

sender: Id

The para that acts as the sender in this channel.

recipient: Id

The para that acts as the recipient in this channel.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for HrmpChannelId

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

where __CodecOutputEdqy: Output + ?Sized,

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

fn encoded_size(&self) -> usize

Calculates the encoded size.

impl Hash for HrmpChannelId

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 Ord for HrmpChannelId

fn cmp(&self, other: &HrmpChannelId) -> 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.

impl PartialEq for HrmpChannelId

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

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.
