Struct Scanner 

pub struct Scanner(InternalScanner);

A transaction scanner to find outputs received.

When an output is successfully scanned, the output key MUST be checked against the local database for lack of prior observation. If it was prior observed, that output is an instance of the burning bug and MAY be unspendable. Only the prior received output(s) or the newly received output will be spendable (as spending one will burn all of them).

Once checked, the output key MUST be saved to the local database so future checks can be performed.

Implementations

impl Scanner

pub fn new(pair: ViewPair) -> Self

Create a Scanner from a ViewPair.

pub fn register_subaddress(&mut self, subaddress: SubaddressIndex)

Register a subaddress to scan for.

Subaddresses must be explicitly registered ahead of time in order to be successfully scanned.

This function runs in variable time, notably with regards to the distribution of subaddress derivations (which should be reasonably uniform) and the amount of subaddresses registered.

pub fn scan(&mut self, block: ScannableBlock) -> Result<Timelocked, ScanError>

Scan a block.

This function runs in variable time, notably with regards to how the private view key relates to outputs present within the block (such as if it can successfully scan outputs present).

Trait Implementations

impl Clone for Scanner

fn clone(&self) -> Scanner

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Drop for Scanner

fn drop(&mut self)

Executes the destructor for this type.

impl Zeroize for Scanner

fn zeroize(&mut self)

Zero out this object from memory using Rust intrinsics which ensure the zeroization operation is not “optimized away” by the compiler.
