Enum sp_core::crypto::DeriveJunction

[−] Show declaration

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

[−] Expand description

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])

[−] Expand description

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

Hard([u8; 32])

[−] Expand description

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.
