Trait ObjectSource 

pub trait ObjectSource {
    // Required methods
    fn get_tree(&self, hash: &ContentHash) -> Result<Option<Tree>>;
    fn get_state(&self, id: &StateId) -> Result<Option<State>>;
    fn get_blob(&self, hash: &ContentHash) -> Result<Option<Blob>>;

    // Provided methods
    fn decoded_blob_len(&self, hash: &ContentHash) -> Result<Option<u64>> { ... }
    fn get_blob_bytes(&self, hash: &ContentHash) -> Result<Option<Bytes>> { ... }
}

Read-only object access needed by object graph walkers.

Required Methods

fn get_tree(&self, hash: &ContentHash) -> Result<Option<Tree>>

fn get_state(&self, id: &StateId) -> Result<Option<State>>

fn get_blob(&self, hash: &ContentHash) -> Result<Option<Blob>>

Provided Methods

fn decoded_blob_len(&self, hash: &ContentHash) -> Result<Option<u64>>

Uncompressed byte length without requiring content.

The default falls back to Self::get_blob. Stores that can answer from a header or index should override this so blame can reject an oversized blob before materializing it.

fn get_blob_bytes(&self, hash: &ContentHash) -> Result<Option<Bytes>>

Zero-copy variant of get_blob.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
