Struct LockedSymbolTable 

pub struct LockedSymbolTable { /* private fields */ }

A thread-safe symbol table with read/write locking.

This wrapper provides concurrent access to a symbol table with read/write locks, transaction support, and lock statistics tracking.

Implementations

impl LockedSymbolTable

pub fn new() -> Self

Create a new locked symbol table.

pub fn from_table(table: SymbolTable) -> Self

Create a locked symbol table from an existing symbol table.

pub fn read(&self) -> RwLockReadGuard<'_, SymbolTable>

Acquire a read lock on the symbol table.

This will block until a read lock can be acquired. Multiple readers can hold locks simultaneously.

pub fn try_read(&self) -> Option<RwLockReadGuard<'_, SymbolTable>>

Try to acquire a read lock without blocking.

Returns Some(guard) if successful, None if would block.

pub fn write(&self) -> RwLockWriteGuard<'_, SymbolTable>

Acquire a write lock on the symbol table.

This will block until a write lock can be acquired. Only one writer can hold a lock at a time, and no readers can be active.

pub fn try_write(&self) -> Option<RwLockWriteGuard<'_, SymbolTable>>

Try to acquire a write lock without blocking.

Returns Some(guard) if successful, None if would block.

pub fn stats(&self) -> LockStats

Get current lock statistics.

pub fn reset_stats(&self)

Reset lock statistics.

pub fn begin_transaction(&self) -> Transaction<'_>

Start a new transaction.

Returns a transaction object that can be committed or rolled back.
