Trait Snapshot 

pub trait Snapshot:
    Send
    + Sync
    + 'static {
    // Provided method
    fn size_bytes(&self) -> usize { ... }
}

Producer-side snapshot of current state. Whatever the consumer needs to bootstrap its local model to match the producer at attach time. For tear: a PaneSnapshot (grid + cursor + flags). For a WebSocket: the last N messages. For a Kubernetes log stream: the tail of stdout up to attach time.

Implementors keep the trait minimal so engate stays generic; transport-specific serialization is the implementor’s concern.

Provided Methods

fn size_bytes(&self) -> usize

Approximate byte size of the snapshot. Used for tracing / metrics (“how much history did we replay on attach?”).

Dyn Compatibility

This trait is dyn compatible.

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