Struct lnp::channel::bolt::LocalKeyset

pub struct LocalKeyset {
    pub funding_pubkey: LocalPubkey,
    pub revocation_basepoint: LocalPubkey,
    pub payment_basepoint: LocalPubkey,
    pub delayed_payment_basepoint: LocalPubkey,
    pub htlc_basepoint: LocalPubkey,
    pub first_per_commitment_point: LocalPubkey,
    pub shutdown_scriptpubkey: Option<PubkeyScript>,
    pub static_remotekey: bool,
}

Set of keys used by the core of the channel. It does not include HTLC basepoint which is managed separately by super::Htlc extension.

Fields

funding_pubkey: LocalPubkey

Public key used in the funding outpoint multisig

revocation_basepoint: LocalPubkey

Base point for deriving keys used for penalty spending paths

payment_basepoint: LocalPubkey

Base point for deriving keys in to_remote

delayed_payment_basepoint: LocalPubkey

Base point for deriving keys in to_local time-locked spending paths

htlc_basepoint: LocalPubkey

Base point for deriving HTLC-related keys

first_per_commitment_point: LocalPubkey

Base point for deriving keys used for penalty spending paths

shutdown_scriptpubkey: Option<PubkeyScript>

Allows the sending node to commit to where funds will go on mutual close, which the remote node should enforce even if a node is compromised later.

static_remotekey: bool

If option_static_remotekey or option_anchors is negotiated, the remotepubkey is simply the remote node’s payment_basepoint, otherwise it is calculated as above using the remote node’s payment_basepoint.

Implementations

impl LocalKeyset

pub fn with<C: Signing>( secp: &Secp256k1<C>, channel_source: KeySource, channel_xpriv: ExtendedPrivKey, shutdown_scriptpubkey: Option<PubkeyScript> ) -> Self

Derives keyset from a channel extended key using LNPBP-46 standard

Trait Implementations

impl Clone for LocalKeyset

fn clone(&self) -> LocalKeyset

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for LocalKeyset

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for LocalKeyset

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

Deserialize this value from the given Serde deserializer.

impl Display for LocalKeyset

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

Formats the value using the given formatter.

impl DumbDefault for LocalKeyset

fn dumb_default() -> Self

Returns an object initialized with dumb data

impl PartialEq<LocalKeyset> for LocalKeyset

fn eq(&self, other: &LocalKeyset) -> 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 Serialize for LocalKeyset

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

Serialize this value into the given Serde serializer.

impl StrictDecode for LocalKeyset

fn strict_decode<D: Read>(d: D) -> Result<Self, Error>

Decode with the given std::io::Read instance; must either construct an instance or return implementation-specific error type.

fn strict_deserialize(data: impl AsRef<[u8]>) -> Result<Self, Error>

Tries to deserialize byte array into the current type using StrictDecode::strict_decode. If there are some data remains in the buffer once deserialization is completed, fails with Error::DataNotEntirelyConsumed. Use io::Cursor over the buffer and StrictDecode::strict_decode to avoid such failures.

fn strict_file_load(path: impl AsRef<Path>) -> Result<Self, Error>

Reads data from file at path and reconstructs object from it. Fails with Error::DataNotEntirelyConsumed if file contains remaining data after the object reconstruction.

impl StrictEncode for LocalKeyset

fn strict_encode<E: Write>(&self, e: E) -> Result<usize, Error>

Encode with the given std::io::Write instance; must return result with either amount of bytes encoded – or implementation-specific error type.

fn strict_serialize(&self) -> Result<Vec<u8, Global>, Error>

Serializes data as a byte array using StrictEncode::strict_encode function

fn strict_file_save(&self, path: impl AsRef<Path>) -> Result<usize, Error>

Saves data to a file at a given path. If the file does not exists, attempts to create the file. If the file already exists, it gets truncated.

impl ToYamlString for LocalKeyset

fn to_yaml_string(&self) -> String

Performs conversion of the self into a YAML-encoded string

impl Eq for LocalKeyset

impl StructuralEq for LocalKeyset

impl StructuralPartialEq for LocalKeyset
