Struct Transaction Announcement &nbsp; Copy item path

impl TransactionAnnouncement

pub fn from_message( msg: &NewPooledTransactionHashes, seen: &mut B256Set, ) -> Result<Self>

Normalizes a wire announcement, keeping the first occurrence of each hash and its metadata. The scratch set is cleared before use and its allocation is kept for subsequent messages, unless an oversized announcement grew it past twice the announcement soft limit.

Returns an error if the hash, type and size arrays have different lengths.

pub const fn version(&self) -> EthVersion

Returns the wire message version.

pub const fn cell_mask(&self) -> Option<B128>

Returns the eth/72 message-level cell mask, if present.

pub const fn len(&self) -> usize

Returns the number of entries.

pub const fn is_empty(&self) -> bool

Returns whether there are no entries.

pub fn iter(&self) -> impl ExactSizeIterator<Item = &AnnouncedTransaction>

Iterates over the entries in announcement order.

pub fn retain(&mut self, f: impl FnMut(&AnnouncedTransaction) -> bool)

Retains entries satisfying the predicate without changing their order.
