Enum PoolFrame 

pub enum PoolFrame {
    Reset,
    Peak {
        height: u32,
        header_hash: Bytes32,
    },
    CoinStates {
        height: u32,
        fork_height: u32,
        peak_hash: Bytes32,
        items: Vec<CoinState>,
    },
    SessionEnded {
        reason: SessionEndReason,
    },
}

One frame from a pooled peer session, as a subscriber sees it.

Carried inside a SourcedFrame, which names the session it belongs to.

Variants

Reset

This session has BEGUN. Anything derived from an earlier session at the same address is stale.

Delivered before any other frame of the session, never after one.

Peak

A peer announced a new peak.

Fields

height: u32

header_hash: Bytes32

CoinStates

A peer reported coin states changing at height.

Fields

height: u32

fork_height: u32

peak_hash: Bytes32

The header hash of the peak this update was observed against.

Carried because CoinStateUpdate carries it and a subscriber tracking the peak needs the height and the hash to arrive TOGETHER. Dropping it forces a subscriber to pair the new height with whatever hash it already had, which names a block that never existed at that height — and does so most often during a reorg, exactly when the pairing is what a consumer is relying on.

items: Vec<CoinState>

SessionEnded

This session has ENDED and will produce no further frames.

A subscriber following this source learns that its stream stopped, rather than being left with a silence it cannot distinguish from a quiet chain.

Fields

reason: SessionEndReason
