Configuration for Queue.

Fields

partition: String

The storage partition name for the queue’s journal.

items_per_section: NonZeroU64

The number of items to store in each journal section.

Larger values reduce file overhead but increase minimum pruning granularity. Once set, this value cannot be changed across restarts.

compression: Option<u8>

Optional zstd compression level for stored items.

If set, items will be compressed before storage. Higher values provide better compression but use more CPU.

Keep the choice between None and Some(_) fixed while stored items are retained. Only the compression level may change between initializations when compression is enabled.

codec_config: C

Codec configuration for encoding/decoding items.

page_cache: CacheRef

Page cache for buffering reads from the underlying journal.

write_buffer: NonZeroUsize

Write buffer size for each section.

replay_buffer: NonZeroUsize

Buffer size for sequential reads during recovery.

Trait Implementations

impl<C: Clone> Clone for Config<C>

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
