Struct TransactionView

pub struct TransactionView<const SANITIZED: bool, D: TransactionData> { /* private fields */ }

A view into a serialized transaction.

This struct provides access to the transaction data without deserializing it. This is done by parsing and caching metadata about the layout of the serialized transaction. The owned data is abstracted through the TransactionData trait, so that different containers for the serialized transaction can be used.

Implementations

impl<D: TransactionData> TransactionView<false, D>

pub fn try_new_unsanitized(data: D) -> Result<Self>

Creates a new TransactionView without running sanitization checks.

pub fn sanitize(self) -> Result<SanitizedTransactionView<D>>

Sanitizes the transaction view, returning a sanitized view on success.

impl<D: TransactionData> TransactionView<true, D>

pub fn try_new_sanitized(data: D) -> Result<Self>

Creates a new TransactionView, running sanitization checks.
