Trait ExternalObjectSource 

pub trait ExternalObjectSource: Send + Sync {
    // Required methods
    fn get_blob(&self, hash: &ContentHash) -> Result<Option<Blob>>;
    fn get_tree(&self, hash: &ContentHash) -> Result<Option<Tree>>;
    fn get_state(&self, id: &StateId) -> Result<Option<State>>;
    fn list_states(&self) -> Result<Vec<StateId>>;
}

Read-only objects whose authoritative representation lives outside the native Heddle object directory. Git-overlay repositories use this seam to translate objects directly from .git without importing a second copy.

Required Methods

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

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

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

fn list_states(&self) -> Result<Vec<StateId>>

Dyn Compatibility

This trait is dyn compatible.

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