Enum IndexStore 

pub enum IndexStore {
    Memory(Vec<PacketIndex>),
    Disk {
        writer: BufWriter<File>,
        path: PathBuf,
        count: u64,
    },
}

Storage backend for the first-pass packet index.

Variants

Memory(Vec<PacketIndex>)

In-memory vector — fast path for captures that fit comfortably in RAM.

Disk

On-disk sidecar file — for TB-scale inputs where the index itself may be large (≈ 20 MB per 1 M packets).

Fields

writer: BufWriter<File>

path: PathBuf

count: u64

Implementations

impl IndexStore

pub fn memory() -> Self

Create an in-memory store.

pub fn disk(sidecar_path: &Path) -> Result<Self, SortError>

Create an on-disk store backed by a file at sidecar_path.

Errors

Returns SortError::Io if the sidecar file cannot be created.

pub fn push(&mut self, entry: PacketIndex) -> Result<(), SortError>

Append one PacketIndex record.

Errors

Returns SortError::Io on write failure (disk mode only).

pub fn sidecar_path(&self) -> Option<&Path>

Return the path of the on-disk sidecar file, if any.

pub fn into_sorted(self) -> Result<Vec<PacketIndex>, SortError>

Flush any buffered writes, sort all entries by timestamp_ns, and return the result as an owned Vec<PacketIndex>.

The on-disk sidecar file is not deleted here; the caller is responsible for cleanup.

Errors

Returns SortError::Io on flush or read failure.
