Struct Scanner 

pub struct Scanner { /* private fields */ }

scanner for trial decryption of Orchard notes

Thread-safe: can be cloned and used from multiple threads. For WASM, process in chunks via async.

Implementations

impl Scanner

pub fn new(ivk: &IncomingViewingKey) -> Self

create scanner from incoming viewing key

pub fn from_fvk(fvk: &FullViewingKey) -> Self

create scanner from full viewing key (external scope)

pub fn from_fvk_scoped(fvk: &FullViewingKey, scope: Scope) -> Self

create scanner from full viewing key with specific scope

pub fn try_decrypt(&self, action: &ScanAction) -> Option<DecryptedNote>

scan a single action, returning decrypted note if owned

pub fn scan_sequential(&self, actions: &[ScanAction]) -> Vec<DecryptedNote>

scan multiple actions sequentially suitable for WASM (no threading) or when parallelism not needed

pub fn scan_parallel(&self, actions: &[ScanAction]) -> Vec<DecryptedNote>

scan multiple actions in parallel using rayon only available on native (not WASM)

pub fn scan(&self, actions: &[ScanAction]) -> Vec<DecryptedNote>

scan actions with automatic parallelism selection uses parallel on native, sequential on WASM

pub fn scan_with_progress<F>( &self, actions: &[ScanAction], chunk_size: usize, on_progress: F, ) -> Vec<DecryptedNote>

where F: FnMut(usize, usize, &[DecryptedNote]),

scan in chunks for progress reporting callback receives (chunk_index, total_chunks, found_notes)
