pub struct SymbolTablePtr
where
    Self: Send + Sync,
{ /* private fields */ }

Implementations

impl SymbolTablePtr

pub fn new() -> Self

Create an empty new SymbolTable and return a shared pointer to it

pub fn with_parent(symbols: SymbolTablePtr) -> Self

Create an empty new SymbolTable with the given parent and return a shared pointer to it

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

Read the underlying symbol table. This will block the current thread until a read lock can be acquired.

WARNING

• If the current thread already holds a lock over this table, this may deadlock.

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

Mutate the underlying symbol table. This will block the current thread until an exclusive write lock can be acquired.

WARNING

• If the current thread already holds a lock over this table, this may deadlock.
• Trying to acquire any other lock until the write lock is released will cause a deadlock.
• This will mutate the underlying data, which may be shared between other SymbolTablePtrs. Make sure that this is what you want.

To create a separate copy of the table, see SymbolTablePtr::detach.

pub fn detach(&self) -> Self

Create a new symbol table with the same contents as this one, but a new ID, and return a pointer to it.

Note: Most layout information is completely unstable and may even differ between compilations. The only exception is types with certain repr(...) attributes. Please see the Rust Reference's “Type Layout” chapter for details on type layout guarantees.
