Function read_blob 

pub fn read_blob<S: ObjectSource + ?Sized>(
    store: &S,
    hash: &Hash,
) -> WorktreeResult<Vec<u8>>

Reassemble the full byte content of a Blob or ChunkedBlob object addressed by hash.

A plain Blob returns its bytes directly. A ChunkedBlob manifest is reassembled by concatenating each referenced chunk (every chunk must itself be a Blob). This is the shared counterpart to store_file_object and backs mkit cat, mkit diff, conflict rendering, and blame so they all reconstruct large-file content the same way.

Errors

• WorktreeError::Store if hash or any chunk is missing.
• WorktreeError::Io if hash (or a chunk) resolves to an object that is neither a Blob nor a ChunkedBlob of Blobs.
• WorktreeError::Object if the concatenated chunks do not total the manifest’s total_size (SPEC-OBJECTS §7).
