Enum sp_core::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) -> Self

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

pub fn harden(self) -> Self

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

pub fn soft<T: Encode>(index: T) -> Self

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

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

pub fn hard<T: Encode>(index: T) -> Self

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

Formats the value using the given formatter.

impl Decode for DeriveJunction

fn decode<__CodecInputEdqy: Input>( __codec_input_edqy: &mut __CodecInputEdqy ) -> Result<Self, Error>

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.

fn encoded_fixed_size() -> Option<usize>

Returns the fixed encoded size of the type.

impl Encode for DeriveJunction

fn size_hint(&self) -> usize

If possible give a hint of expected size of the encoding.

fn encode_to<__CodecOutputEdqy: Output + ?Sized>( &self, __codec_dest_edqy: &mut __CodecOutputEdqy )

Convert self to a slice and append it to the destination.

fn encode(&self) -> Vec<u8>

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.

fn encoded_size(&self) -> usize

impl<T: AsRef<str>> From<T> for DeriveJunction

fn from(j: T) -> DeriveJunction

Converts to this type from the input type.

impl Hash for DeriveJunction

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

impl PartialEq for DeriveJunction

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

This method tests for self and other values to be equal, and is used by ==.

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
