Trait DatumStore 

Source 
pub trait DatumStore {
    // Required methods
    fn intern(&mut self, datum: Datum) -> Result<ContentId>;
    fn get(&self, id: &ContentId) -> Result<Option<&Datum>>;
    fn contains(&self, id: &ContentId) -> bool;
}
Expand description

Contract for interning and resolving content-addressed Datums.

This is protocol the libraries implement; the kernel ships a simple BTreeDatumStore but defines no persistent storage policy.

Required Methods§

Source

fn intern(&mut self, datum: Datum) -> Result<ContentId>

Interns datum, returning its ContentId; re-interning equal data is idempotent.

Source

fn get(&self, id: &ContentId) -> Result<Option<&Datum>>

Resolves the datum for id, or None when it is not stored here.

Source

fn contains(&self, id: &ContentId) -> bool

Returns whether id is interned in this store.

Dyn Compatibility§

This trait is dyn compatible.

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