Trait RingFrameSource 

pub trait RingFrameSource {
    // Required methods
    fn kind(&self) -> u8;
    fn head(&self) -> u64;
    fn capacity(&self) -> usize;
    fn read_at(&self, counter: u64) -> Option<Frame>;
}

Read-only source that can be walked by super::RingCursor.

Implementors expose only the ring facts needed by the generic walker: the ring kind, current head, fixed capacity, and counter-addressed frame reads.

Required Methods

fn kind(&self) -> u8

The OrbitTyped::KIND carried by this ring.

fn head(&self) -> u64

Monotonic write head: number of writes ever published.

fn capacity(&self) -> usize

Fixed slot count for this ring.

fn read_at(&self, counter: u64) -> Option<Frame>

Read the frame currently occupying counter % capacity.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
