Struct CompactionContext 

pub struct CompactionContext<'a> {
    pub backend: Option<&'a dyn CompactionBackend>,
    pub cancellation: Option<TurnCancellation>,
}

Runtime context passed to each CompactionStrategy during execution.

Provides access to an optional CompactionBackend (needed by SummarizeOlderStrategy), shared metadata, and a cancellation token that strategies should respect.

Fields

backend: Option<&'a dyn CompactionBackend>

An optional backend for strategies that need to call an external summarisation service.

cancellation: Option<TurnCancellation>

Cancellation token; strategies should check this and return CompactionError::Cancelled when signalled.
