Expand description

Read-only object access needed by object graph walkers.

Required Methods§

Source

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

Source

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

Source

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

Provided Methods§

Source

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

Zero-copy variant of get_blob.

Dyn Compatibility§

This trait is dyn compatible.

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