Struct FragmentIndex 

pub struct FragmentIndex { /* private fields */ }

In-memory index: chunk_id → Vec<FragmentMeta>.

Keyed by chunk_id so that the storage manager can quickly find all fragments of a given chunk (for recoding or proof-of-storage responses).

Implementations

impl FragmentIndex

pub fn new() -> Self

Create an empty index.

pub fn insert(&mut self, meta: FragmentMeta)

Register a new fragment.

pub fn remove( &mut self, chunk_id: &str, fragment_id: &str, ) -> Option<FragmentMeta>

Remove a fragment by chunk_id + fragment_id. Returns the removed entry if found.

pub fn fragments_for_chunk(&self, chunk_id: &str) -> &[FragmentMeta]

All fragment records for a given chunk (for recoding / PoS challenges).

pub fn chunk_ids(&self) -> impl Iterator<Item = &str>

All chunk IDs tracked.

pub fn fragment_count(&self) -> usize

Total number of fragments across all chunks.

pub fn total_bytes(&self) -> u64

Total bytes occupied by all stored fragments.

pub fn contains_chunk(&self, chunk_id: &str) -> bool

Whether the index holds any fragment for the given chunk.

Trait Implementations

impl Debug for FragmentIndex

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FragmentIndex

fn default() -> FragmentIndex

Returns the “default value” for a type.
