Enum gclient::ext::sp_runtime::app_crypto::DeriveJunction

pub enum DeriveJunction {
    Soft([u8; 32]),
    Hard([u8; 32]),
}

A since derivation junction description. It is the single parameter used when creating a new secret key from an existing secret key and, in the case of SoftRaw and SoftIndex a new public key from an existing public key.

Variants

Soft([u8; 32])

Soft (vanilla) derivation. Public keys have a correspondent derivation.

Hard([u8; 32])

Hard (“hardened”) derivation. Public keys do not have a correspondent derivation.

Implementations

impl DeriveJunction

pub fn soften(self) -> DeriveJunction

Consume self to return a soft derive junction with the same chain code.

pub fn harden(self) -> DeriveJunction

Consume self to return a hard derive junction with the same chain code.

pub fn soft<T>(index: T) -> DeriveJunction

where T: Encode,

Create a new soft (vanilla) DeriveJunction from a given, encodable, value.

If you need a hard junction, use hard().

pub fn hard<T>(index: T) -> DeriveJunction

where T: Encode,

Create a new hard (hardened) DeriveJunction from a given, encodable, value.

If you need a soft junction, use soft().

pub fn unwrap_inner(self) -> [u8; 32]

Consume self to return the chain code.

pub fn inner(&self) -> &[u8; 32]

Get a reference to the inner junction id.

pub fn is_soft(&self) -> bool

Return true if the junction is soft.

pub fn is_hard(&self) -> bool

Return true if the junction is hard.

Trait Implementations

impl Clone for DeriveJunction

fn clone(&self) -> DeriveJunction

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for DeriveJunction

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

where __CodecInputEdqy: Input,

Attempt to deserialise the value from input.

fn decode_into<I>( input: &mut I, dst: &mut MaybeUninit<Self>, ) -> Result<DecodeFinished, Error>

where I: Input,

Attempt to deserialize the value from input into a pre-allocated piece of memory.

fn skip<I>(input: &mut I) -> Result<(), Error>

where I: Input,

Attempt to skip the encoded value from input.

Convert self to an owned vector.

fn using_encoded<R, F>(&self, f: F) -> R

where F: FnOnce(&[u8]) -> R,

Convert self to a slice and then invoke the given closure with it.

impl<T> From<T> for DeriveJunction

where T: AsRef<str>,

fn from(j: T) -> DeriveJunction

Converts to this type from the input type.

impl Hash for DeriveJunction

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

impl PartialEq for DeriveJunction

fn eq(&self, other: &DeriveJunction) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool
