Struct ln_types::node_pubkey::NodePubkey

pub struct NodePubkey(pub PublicKey);

This is supported on crate feature secp256k1 only.

Newtype over secp256k1::PublicKey representing a deserialized key identifying an LN node.

This can be considered similar to NodeId with these differences:

• NodeId is more performant for non-cryptographic operations.
• NodeId can not perform any cryptographic operations itself.
• NodePubkey, despite its field being public, maintains more invariants. In this library, a valid NodeId is not guaranteed to be a valid NodePubkey

Tuple Fields

0: PublicKey

The underlying public key used for cryptographic operations.

Implementations

impl NodePubkey

pub fn to_node_id(&self) -> NodeId

Convenience conversion method.

This is more readable and less prone to inference problems than Into::into.

pub fn from_secret_key<C: Signing>(secp: &Secp256k1<C>, sk: &SecretKey) -> Self

Computes public key from a secret key and stores it as NodePubkey.
