    // Required method
    fn merge_single_output<'life0, 'async_trait>(
        &'life0 self,

       where Self: 'async_trait,
             'life0: 'async_trait;
}

Trait for merging a single compaction output into SST files.

This is extracted from DefaultCompactor to allow injecting mock implementations in tests.

Required Methods

fn merge_single_output<'life0, 'async_trait>( &'life0 self, context: CompactionContext, output: CompactionOutput, write_opts: WriteOptions, ) -> Pin<Box<dyn Future<Output = Result<(Vec<FileMeta>, Vec<SstInfo>)>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

Dyn Compatibility

This trait is dyn compatible.

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