Struct breez_sdk_liquid::lightning::ln::ChannelId

pub struct ChannelId(pub [u8; 32]);

A unique 32-byte identifier for a channel. Depending on how the ID is generated, several varieties are distinguished (but all are stored as 32 bytes): v1 and temporary. A v1 channel ID is generated based on funding tx outpoint (txid & index). A temporary ID is generated randomly. (Later revocation-point-based v2 is a possibility.) The variety (context) is not stored, it is relevant only at creation.

This is not exported to bindings users as we just use [u8; 32] directly.

Implementations

impl ChannelId

pub fn v1_from_funding_txid(txid: &[u8; 32], output_index: u16) -> ChannelId

Create v1 channel ID based on a funding TX ID and output index

pub fn temporary_from_entropy_source<ES>(entropy_source: &ES) -> ChannelId

where ES: Deref, <ES as Deref>::Target: EntropySource,

Create a temporary channel ID randomly, based on an entropy source.

pub fn from_bytes(data: [u8; 32]) -> ChannelId

Generic constructor; create a new channel ID from the provided data. Use a more specific *_from_* constructor when possible.

pub fn new_zero() -> ChannelId

Create a channel ID consisting of all-zeros data (e.g. when uninitialized or a placeholder).

pub fn is_zero(&self) -> bool

Check whether ID is consisting of all zeros (uninitialized)

Trait Implementations

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<(), Error>

Formats the value using the given formatter.

impl Display for ChannelId

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

Formats the value using the given formatter.

impl Hash for ChannelId

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 ChannelId

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

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

where Self: Sized,

Compares and returns the minimum of two values.

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

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for ChannelId

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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

impl Readable for ChannelId

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

where R: Read,

Reads a Self in from the given Read.

impl ToHex for ChannelId

fn to_hex(&self) -> String

Converts to a hexadecimal representation of the object.

impl Writeable for ChannelId

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

where W: Writer,

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.
