Struct Mempool 

pub struct Mempool { /* private fields */ }

Mempool data structure: transaction IDs plus outpoints spent by those transactions.

Implementations

impl Mempool

pub fn new() -> Mempool

pub fn insert(&mut self, txid: [u8; 32]) -> bool

Insert a transaction ID only (does not register spent outpoints).

Prefer insert_transaction when the full transaction is available — conflict detection requires outpoint indexing.

pub fn insert_transaction(&mut self, tx: &Transaction) -> bool

Register a transaction and index its spent inputs for conflict detection.

pub fn contains(&self, txid: &[u8; 32]) -> bool

pub fn spends_outpoint(&self, outpoint: &OutPoint) -> bool

pub fn remove(&mut self, txid: &[u8; 32]) -> bool

pub fn remove_spending_any( &mut self, outpoints: &HashSet<OutPoint>, ) -> Vec<[u8; 32]>

Remove mempool entries that spend any of the given outpoints (e.g. after block connect).

pub fn len(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn iter(&self) -> impl Iterator<Item = &[u8; 32]>

pub fn clear(&mut self)

pub fn total_vbytes(&self) -> usize

Total virtual size of transactions indexed via insert_transaction.

Trait Implementations

impl Clone for Mempool

fn clone(&self) -> Mempool

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Mempool

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Default for Mempool

fn default() -> Mempool

Returns the “default value” for a type.

impl Eq for Mempool

impl PartialEq for Mempool

fn eq(&self, other: &Mempool) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
