Channel describes a bridge to exchange messages between two chains.

Fields

channel_id: ChannelId

Channel identifier.

state: ChannelState

State of the channel.

next_inbox_nonce: Nonce

Next inbox nonce.

next_outbox_nonce: Nonce

Next outbox nonce.

latest_response_received_message_nonce: Option<Nonce>

Latest outbox message nonce for which response was received from dst_chain.

max_outgoing_messages: u32

Maximum outgoing non-delivered messages.

fee: FeeModel<Balance>

Fee model for this channel between the chains.

maybe_owner: Option<AccountId>

Owner of the channel Owner maybe None if the channel was initiated on the other chain.

channel_reserve_fee: Balance

The amount of funds put on hold by the owner account for this channel

Trait Implementations

impl<Balance: Clone, AccountId: Clone> Clone for Channel<Balance, AccountId>

fn clone(&self) -> Channel<Balance, AccountId>

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<Balance: Debug, AccountId: Debug> Debug for Channel<Balance, AccountId>

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

Formats the value using the given formatter.

impl<Balance, AccountId> Decode for Channel<Balance, AccountId>

where FeeModel<Balance>: Decode, Option<AccountId>: Decode, Balance: Decode,

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy, ) -> Result<Self, Error>

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

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<Balance: Default, AccountId: Default> Default for Channel<Balance, AccountId>

fn default() -> Channel<Balance, AccountId>

Returns the “default value” for a type.

impl<Balance, AccountId> Encode for Channel<Balance, AccountId>

where FeeModel<Balance>: Encode, Option<AccountId>: Encode, Balance: Encode,

fn size_hint(&self) -> usize

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

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy, )

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<Balance: PartialEq, AccountId: PartialEq> PartialEq for Channel<Balance, AccountId>

fn eq(&self, other: &Channel<Balance, AccountId>) -> 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.
