Struct StorageIndexBuilder 

pub struct StorageIndexBuilder {
    pub entries: HashMap<String, IndexEntry>,
}

Builds and maintains a secondary index over block metadata.

Example

use ipfrs_storage::index_builder::{
    IndexEntry, QueryFilter, StorageIndexBuilder,
};

let mut idx = StorageIndexBuilder::new();
idx.insert(IndexEntry {
    cid: "QmA".into(),
    size_bytes: 1024,
    created_at_secs: 1_000,
    tags: vec!["audio".into()],
    content_type: "audio/mpeg".into(),
});

let results = idx.query(&QueryFilter::HasTag { tag: "audio".into() });
assert_eq!(results.len(), 1);

Fields

entries: HashMap<String, IndexEntry>

Primary storage: CID → IndexEntry.

Implementations

impl StorageIndexBuilder

pub fn new() -> Self

Creates an empty index.

pub fn insert(&mut self, entry: IndexEntry)

Inserts (or replaces) an entry keyed by its CID.

pub fn remove(&mut self, cid: &str) -> bool

Removes the entry with the given CID.

Returns true if an entry was present and removed, false otherwise.

pub fn query(&self, filter: &QueryFilter) -> Vec<&IndexEntry>

Returns all entries that satisfy filter, sorted by created_at_secs ascending.

pub fn update_tags(&mut self, cid: &str, tags: Vec<String>) -> bool

Replaces the tag list for the entry identified by cid.

Returns true if the entry was found and updated, false otherwise.

pub fn stats(&self) -> IndexStats

Returns summary statistics for the current index state.

Trait Implementations

impl Default for StorageIndexBuilder

fn default() -> Self

Returns the “default value” for a type.
