Struct grin_keychain::view_key::ViewKey

pub struct ViewKey {
    pub is_test: bool,
    pub depth: u8,
    pub child_number: ChildNumber,
    pub rewind_hash: Vec<u8>,
    /* private fields */
}

Key that can be used to scan the chain for owned outputs This is a public key, meaning it cannot be used to spend those outputs At the moment only depth 0 keys can be used

Fields

is_test: bool

Whether this view key is meant for testnet or not

depth: u8

How many derivations this key is from the master (which is 0)

child_number: ChildNumber

Child number of the key used to derive from parent (0 for master)

rewind_hash: Vec<u8>

Hash used to generate rewind nonce

Implementations

impl ViewKey

pub fn create<K, H>( keychain: &K, ext_key: ExtendedPrivKey, hasher: &mut H, is_test: bool ) -> Result<Self, Error>

where K: Keychain, H: BIP32Hasher,

pub fn rewind_hash(secp: &Secp256k1, public_root_key: PublicKey) -> Vec<u8>

pub fn ckd_pub<H>( &self, secp: &Secp256k1, hasher: &mut H, i: ChildNumber ) -> Result<Self, Error>

where H: BIP32Hasher,

pub fn commit( &self, secp: &Secp256k1, amount: u64, switch: SwitchCommitmentType ) -> Result<PublicKey, Error>

Trait Implementations

impl Clone for ViewKey

fn clone(&self) -> ViewKey

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ViewKey

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

Formats the value using the given formatter.

impl PartialEq for ViewKey

fn eq(&self, other: &ViewKey) -> 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.
