Struct grin_keychain::view_key::ViewKey

pub struct ViewKey {
    pub is_floo: bool,
    pub depth: u8,
    pub child_number: ChildNumber,
    pub rewind_hash: Vec<u8>,
    // some fields omitted
}

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_floo: bool

Whether this view key is meant for floonet 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

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 Eq for ViewKey

impl PartialEq<ViewKey> 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: &ViewKey) -> bool

This method tests for !=.

impl Debug for ViewKey

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

Formats the value using the given formatter.
