Struct grin_keychain::ExtKeychainPath

pub struct ExtKeychainPath {
    pub depth: u8,
    pub path: [ChildNumber; 4],
}

Encapsulates a max 4-level deep BIP32 path, which is the most we can currently fit into a rangeproof message. The depth encodes how far the derivation depths go and allows differentiating paths. As m/0, m/0/0 or m/0/0/0/0 result in different derivations, a path needs to encode its maximum depth.

Fields

depth: u8

path: [ChildNumber; 4]

Methods

impl ExtKeychainPath

pub fn new(depth: u8, d0: u32, d1: u32, d2: u32, d3: u32) -> ExtKeychainPath

Return a new chain path with given derivation and depth

pub fn from_identifier(id: &Identifier) -> ExtKeychainPath

from an Indentifier [manual deserialization]

pub fn to_identifier(&self) -> Identifier

to an Identifier [manual serialization]

pub fn last_path_index(&self) -> u32

Last part of the path (for last n_child)
