source · pub struct DerivationPath(/* private fields */);
Expand description
According to BIP-44 https://github.com/bitcoin/bips/blob/master/bip-0044.mediawiki and EIP-3 https://github.com/ergoplatform/eips/blob/master/eip-0003.md
Implementations§
source§impl DerivationPath
impl DerivationPath
sourcepub fn new(
acc: ChildIndexHardened,
address_indices: Vec<ChildIndexNormal>
) -> Self
pub fn new( acc: ChildIndexHardened, address_indices: Vec<ChildIndexNormal> ) -> Self
Create derivation path for a given account index (hardened) and address indices
m / 44' / 429' / acc' / 0 / address[0] / address[1] / ...
or m / 44' / 429' / acc' / 0
if address indices are empty
change is always zero according to EIP-3
sourcepub fn master_path() -> Self
pub fn master_path() -> Self
Create root derivation path
sourcepub fn extend(&self, index: ChildIndex) -> DerivationPath
pub fn extend(&self, index: ChildIndex) -> DerivationPath
Extend the path with the given index. Returns this derivation path with added index.
sourcepub fn next(&self) -> Result<DerivationPath, DerivationPathError>
pub fn next(&self) -> Result<DerivationPath, DerivationPathError>
Returns a new path with the last element of the deriviation path being increased, e.g. m/1/2 -> m/1/3 Returns an empty path error if the path is empty (master node for example)
