Struct TransactionViews 

pub struct TransactionViews<'t> { /* private fields */ }

Every transaction view of a message, prepared once.

AssembledTree::transaction_view finds what a view leaves out by walking every other transaction, and the caller then filters the whole message by it: one view costs as much as the message, all of them its square — 1,600 UTILMD transactions took 1.6 s for the views alone. This sorts each segment once into what every view of a kind keeps and what only one transaction’s view keeps, so a view costs its own transaction plus what the transactions share (the header, SG2, …).

Implementations

impl TransactionViews<'_>

pub fn view( &self, group_id: &str, index: usize, ) -> Option<TransactionSegmentsView>

Transaction index of the top-level group group_id, as AssembledTree::transaction_view gives it, with the message segments it keeps. None when the group is no transaction group or has no such repetition.
