Struct Gc

pub struct Gc<T: Trace> { /* private fields */ }

A Garbage-Collected smart pointer with interior mutability.

Implementations

impl<T: Trace> Gc<T>

pub fn new(data: T) -> Gc<T>

impl<T: Trace> Gc<T>

pub unsafe fn as_opaque(&self) -> OpaqueGcPtr

Safety

This function is not safe and basically useless for anything outside of the Trace proc macro’s generated code.

pub async fn read(&self) -> GcReadGuard<'_, T>

Acquire a read lock for the object

pub fn try_read(&self) -> Option<GcReadGuard<'_, T>>

Attempt to acquire a read lock for the object

pub async fn write(&self) -> GcWriteGuard<'_, T>

Acquire a write lock for the object
