Struct trie_db::BytesWeak

source ·
pub struct BytesWeak(/* private fields */);
Expand description

A weak reference of Bytes.

A weak reference means that it doesn’t prevent Bytes from being dropped because it holds a non-owning reference to the associated Bytes object. With Self::upgrade it is possible to upgrade it again to Bytes if the reference is still valid.

Implementations§
