Struct StorageBlockPacker

Source

pub struct StorageBlockPacker {
    pub packs: HashMap<u64, Pack>,
    pub next_pack_id: u64,
    pub config: PackerConfig,
}

Expand description

Packs multiple small blocks into larger pack files for efficient storage.

Fields§

§packs: HashMap<u64, Pack>

All packs, keyed by pack_id.

§next_pack_id: u64

The next pack_id to assign.

§config: PackerConfig

Configuration controlling packing behavior.

Implementations§

Source §

impl StorageBlockPacker

Source

pub fn new(config: PackerConfig) -> Self

Creates a new StorageBlockPacker with the given configuration.

Source

pub fn pack(&mut self, blocks: Vec<(String, u64)>, now_secs: u64) -> Vec<u64>

Packs a list of (cid, size_bytes) blocks into one or more pack files.

Only blocks where size_bytes < min_block_size_bytes are eligible. Blocks are greedily packed: a new pack is started whenever the current pack would exceed max_pack_size_bytes or max_entries_per_pack.

Returns the list of newly created pack IDs (empty if no eligible blocks).

Source

pub fn find_pack(&self, cid: &str) -> Option<(&Pack, &PackEntry)>

Searches all packs for the given CID.

Returns Some((&Pack, &PackEntry)) if found, None otherwise.

Source

pub fn get_pack(&self, pack_id: u64) -> Option<&Pack>

Returns a reference to the pack with the given ID, or None.

Source

pub fn delete_pack(&mut self, pack_id: u64) -> bool

Removes the pack with the given ID.

Returns true if the pack existed and was removed, false otherwise.

Source

pub fn stats(&self) -> PackerStats

Computes aggregate statistics over all packs.
