temporary_channel_id: [u8; 32]

A random nonce identifying the channel until the fund transaction is created.

contract_info: ContractInfo

Implementations

impl OfferChannel

pub fn validate<C: Verification>( &self, secp: &Secp256k1<C>, min_timeout_interval: u32, max_timeout_interval: u32, min_cet_nsequence: u32, max_cet_nsequence: u32, ) -> Result<(), Error>

Returns whether the message satisfies validity requirements.

Trait Implementations

impl Clone for OfferChannel

fn clone(&self) -> OfferChannel

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for OfferChannel

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

Formats the value using the given formatter.

impl PartialEq for OfferChannel

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

impl Readable for OfferChannel

fn read<R: Read>(r: &mut R) -> Result<Self, DecodeError>

Reads a Self in from the given Read.

impl Type for OfferChannel

fn type_id(&self) -> u16

Returns the type identifying the message payload.

impl Writeable for OfferChannel

fn write<W: Writer>(&self, w: &mut W) -> Result<(), Error>

Writes self out to the given Writer.

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

Writes self out to a Vec<u8>.

fn serialized_length(&self) -> usize

Gets the length of this object after it has been serialized. This can be overridden to optimize cases where we prepend an object with its length.
