Crate rstr 

rstr is a library for managing a content-addressable blob store.

The BlobStore struct manages the interaction with the blob store. An entry in the blob store is represented by an instance of the struct BlobRef.

Examples

Add files or directories to the blob store:

use rstr::{BlobStore,BlobRef};
use std::path::{Path, PathBuf};

let blob_store = BlobStore::new("../tests/test_data_store").unwrap();
let n_threads: u8 = 8;
let (blob_refs_with_paths, _): (Vec<(PathBuf, BlobRef)>, _) = blob_store.add_files(
    &[
        // Can add files
        Path::new("../tests/test_file.txt"),
        // or directories
        Path::new("tests/"),
    ],
    n_threads,
);
let blob_refs: Vec<BlobRef> = blob_refs_with_paths.into_iter().map(|(_, b)| b).collect();

Retrieve a blob from the blob store

use rstr::{BlobStore, BlobRef};

let blob_store = BlobStore::new("../tests/test_data_store").unwrap();

// Retrieve a blob from the blob store
let reference = "f29bc64a9d3732b4b9035125fdb3285f5b6455778edca72414671e0ca3b2e0de";
let blob_ref = BlobRef::new(reference).unwrap();

assert!(blob_store.exists(&blob_ref));

// Get the blob's content
let content = blob_store.get(&blob_ref).unwrap();

// Get the blob's metadata
let metadata = blob_store.metadata(&blob_ref).unwrap();
assert_eq!(metadata.filename, "test_file.txt");
assert_eq!(metadata.mime_type, "text/plain");
