Struct cml_crypto_wasm::Bip32PublicKey

pub struct Bip32PublicKey(/* private fields */);

Implementations

impl Bip32PublicKey

pub fn derive(&self, index: u32) -> Result<Bip32PublicKey, JsError>

derive this public key with the given index.

Errors

If the index is not a soft derivation index (< 0x80000000) then calling this method will fail.

Security considerations

• hard derivation index cannot be soft derived with the public key

Hard derivation vs Soft derivation

If you pass an index below 0x80000000 then it is a soft derivation. The advantage of soft derivation is that it is possible to derive the public key too. I.e. derivation the private key with a soft derivation index and then retrieving the associated public key is equivalent to deriving the public key associated to the parent private key.

Hard derivation index does not allow public key derivation.

This is why deriving the private key should not fail while deriving the public key may fail (if the derivation index is invalid).

Trait Implementations

impl AsRef<Bip32PublicKey> for Bip32PublicKey

fn as_ref(&self) -> &Bip32PublicKey

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for Bip32PublicKey

fn clone(&self) -> Bip32PublicKey

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl From<Bip32PublicKey> for Bip32PublicKey

fn from(inner: Bip32PublicKey) -> Self

Converts to this type from the input type.

impl From<Bip32PublicKey> for Bip32PublicKey

fn from(wrapper: Bip32PublicKey) -> Self

Converts to this type from the input type.

impl From<Bip32PublicKey> for JsValue

fn from(value: Bip32PublicKey) -> Self

Converts to this type from the input type.

impl FromWasmAbi for Bip32PublicKey

type Abi = u32

The wasm ABI type that this converts from when coming back out from the ABI boundary.

unsafe fn from_abi(js: u32) -> Self

Recover a Self from Self::Abi.

impl IntoWasmAbi for Bip32PublicKey

type Abi = u32

The wasm ABI type that this converts into when crossing the ABI boundary.

fn into_abi(self) -> u32

Convert self into Self::Abi so that it can be sent across the wasm ABI boundary.

impl OptionFromWasmAbi for Bip32PublicKey

fn is_none(abi: &Self::Abi) -> bool

Tests whether the argument is a “none” instance. If so it will be deserialized as None, and otherwise it will be passed to FromWasmAbi.

impl OptionIntoWasmAbi for Bip32PublicKey

fn none() -> Self::Abi

Returns an ABI instance indicating “none”, which JS will interpret as the None branch of this option.

impl RefFromWasmAbi for Bip32PublicKey

type Abi = u32

The wasm ABI type references to Self are recovered from.

type Anchor = Ref<'static, Bip32PublicKey>

The type that holds the reference to Self for the duration of the invocation of the function that has an &Self parameter. This is required to ensure that the lifetimes don’t persist beyond one function call, and so that they remain anonymous.

unsafe fn ref_from_abi(js: Self::Abi) -> Self::Anchor

Recover a Self::Anchor from Self::Abi.

impl RefMutFromWasmAbi for Bip32PublicKey

type Abi = u32

Same as RefFromWasmAbi::Abi

type Anchor = RefMut<'static, Bip32PublicKey>

Same as RefFromWasmAbi::Anchor

unsafe fn ref_mut_from_abi(js: Self::Abi) -> Self::Anchor

Same as RefFromWasmAbi::ref_from_abi

impl WasmDescribe for Bip32PublicKey
