Struct DoubleBuffer 

pub struct DoubleBuffer<T> { /* private fields */ }

A double-buffered exchange for efficient producer/consumer handoff.

The producer writes to the “back” buffer while the consumer reads from the “front” buffer. When the producer is done writing, it swaps the buffers (atomically from the consumer’s perspective).

Implementations

impl<T: Clone> DoubleBuffer<T>

pub fn new(initial: T) -> Self

Create a double buffer with two copies of initial.

pub fn read_front(&self) -> CoreResult<T>

Read a clone of the current front buffer.

pub fn write_and_swap<F>(&self, f: F) -> CoreResult<()>

where F: FnOnce(&mut T),

Write to the back buffer via a closure, then swap.

pub fn wait_and_read(&self, timeout: Duration) -> CoreResult<Option<T>>

Block until a new frame is available, then read it.

pub fn publish(&self, value: T) -> CoreResult<()>

Replace the back buffer entirely, then swap.
