Struct MemPoolInner

pub struct MemPoolInner { /* private fields */ }

Inner mempool state (protected by RwLock in main MemPool).

Implementations

impl MemPoolInner

pub fn new() -> Self

Create new empty mempool inner state.

pub fn get_entry(&self, txid: &Txid) -> Option<&TxMemPoolEntry>

Get entry by txid.

pub fn contains_txid(&self, txid: &Txid) -> bool

Check if transaction exists in mempool by txid.

pub fn contains_wtxid(&self, wtxid: &Wtxid) -> bool

Check if transaction exists in mempool by wtxid.

pub fn get_conflict_tx(&self, outpoint: &COutPoint) -> Option<Txid>

Get transaction that spends the given outpoint (conflict detection).

pub fn calculate_descendants( &self, entry_id: EntryId, descendants: &mut HashSet<EntryId>, )

Calculate descendants of a transaction (recursively).

Returns set of all descendant entry IDs (including the starting entry).

pub fn calculate_ancestors( &self, entry_id: EntryId, ancestors: &mut HashSet<EntryId>, )

Calculate ancestors of a transaction (recursively).

Returns set of all ancestor entry IDs (including the starting entry).

pub fn remove_staged( &mut self, to_remove: &HashSet<EntryId>, update_descendants: bool, _reason: RemovalReason, )

Remove transactions and update state.

This is the core removal function that:

• Removes entries from arena
• Updates map_next_tx
• Updates statistics
• Optionally updates ancestor/descendant state for surviving children (RBF)

pub fn trim_to_size(&mut self, max_size: u64)

Trim mempool to maximum size by evicting lowest-feerate transactions.

pub fn expire(&mut self, current_time: i64, max_age_seconds: i64)

Expire old transactions.

pub fn size(&self) -> usize

Get total number of transactions.

pub fn total_size(&self) -> u64

Get total transaction size in bytes.

pub fn total_fees(&self) -> Amount

Get total fees.

impl Default for MemPoolInner

fn default() -> Self

Returns the “default value” for a type.
