Struct ext_sort::sort::ExternalSorterBuilder

pub struct ExternalSorterBuilder<T, E, B = LimitedBufferBuilder, C = RmpExternalChunk<T>>where
    T: Send,
    E: Error,
    B: ChunkBufferBuilder<T>,
    C: ExternalChunk<T>,{ /* private fields */ }

External sorter builder. Provides methods for ExternalSorter initialization.
