Struct trie_db::BytesWeak

source · [−]

pub struct BytesWeak(_);

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

source

impl BytesWeak

source

pub fn upgrade(&self) -> Option<Bytes>
