Struct Deriver 

pub struct Deriver<'a> { /* private fields */ }

Casper address deriver from a unified wallet seed.

Default algorithm is KeyAlgo::Secp256k1 (Ledger path). Switch with with_algo or per-call derive_with.

Implementations

impl<'a> Deriver<'a>

pub const fn new(wallet: &'a Wallet) -> Self

Create a deriver with the default algorithm (KeyAlgo::Secp256k1).

pub const fn with_algo(wallet: &'a Wallet, algo: KeyAlgo) -> Self

Create a deriver locked to algo for Derive::derive / Derive::derive_path.

pub const fn algo(&self) -> KeyAlgo

Algorithm used by Derive::derive and Derive::derive_path.

pub fn derive(&self, index: u32) -> Result<CasperAccount, DeriveError>

Derive at the default path for the deriver’s algorithm.

Errors

Returns an error if key derivation or AccountHash hashing fails.

pub fn derive_with( &self, algo: KeyAlgo, index: u32, ) -> Result<CasperAccount, DeriveError>

Derive at the default path for an explicit algorithm.

Errors

Returns an error if key derivation or AccountHash hashing fails.

pub fn derive_at(&self, path: &str) -> Result<CasperAccount, DeriveError>

Derive at an arbitrary path using the deriver’s stored algorithm for tagging / AccountHash.

Prefer derive_at_with when the path and algorithm must be specified together.

Errors

Returns an error if key derivation or AccountHash hashing fails.

pub fn derive_at_with( &self, path: &str, algo: KeyAlgo, ) -> Result<CasperAccount, DeriveError>

Derive at an arbitrary path with an explicit algorithm (encoding).

The path must be valid for the curve of algo (BIP-32 for secp, fully hardened SLIP-10 for Ed25519).

Errors

Returns an error if key derivation or AccountHash hashing fails.

Trait Implementations

impl<'a> Debug for Deriver<'a>

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

Formats the value using the given formatter.

impl Derive for Deriver<'_>

type Account = CasperAccount

The (possibly newtype) account returned by this deriver.

type Error = DeriveError

The error type returned by derivation operations.

fn derive(&self, index: u32) -> Result<CasperAccount, DeriveError>

Derive an account at the given index using the chain’s default path.

fn derive_path(&self, path: &str) -> Result<CasperAccount, DeriveError>

Derive an account at a custom path string.
