Trait mmtkvdb::storable::StorableRef
source · [−]pub unsafe trait StorableRef<'a, T> where
Self: Sized + Copy,
T: ?Sized + Storable + 'a, {
fn ref_to_bytes(self) -> T::BytesRef<'a>;
fn ref_bytes_len(self) -> usize { ... }
}Expand description
Reference-like types which can be used to store a Storable type
Type parameter T is the Storable type and 'a is the lifetime used for
the reference-like type.
For example, (&'a i32, &'a str) implements
StorableRef<'a, (i32, String)> and may thus be passed to
TxnRw::put instead of &'a (i32, String).
This avoids unnecessary cloning when constructing the tuple.
