Struct ln_types::node_id::NodeId

pub struct NodeId(_);

Byte representation of a node identifier.

This type is used when referring to nodes without doing cryptographic operations. It can be used in search algorithms, LN explorers, manager UIs etc. By avoiding cryptography it is significantly more performant but may make debugging harder. It is therefore recommended to perform checking at system boundaries where performance is not very important - e.g. user inputs.

Implementations

impl NodeId

pub fn from_raw_bytes(bytes: [u8; 33]) -> Self

Creates NodeId from raw byte representation.

pub fn to_vec(self) -> Vec<u8>

Puts the byte representation into Vec<u8>.

This is meant for convenience around APIs that require Vec<u8>. Since it allocates it’s best to avoid it if possible.

pub fn to_array(self) -> [u8; 33]

Convenience conversion to byte array.

This can be used instead of From to avoid inference issues.
