pub struct Snapshot<DB>where
    DB: ParallelDatabase,{ /* private fields */ }

Expand description

Simple wrapper struct that takes ownership of a database DB and only gives &self access to it. See the snapshot method for more details.

Implementations

source

impl<DB> Snapshot<DB>where
DB: ParallelDatabase,

source

pub fn new(db: DB) -> Self

Creates a Snapshot that wraps the given database handle db. From this point forward, only shared references to db will be possible.

Trait Implementations

source

impl<DB: Debug> Debug for Snapshot<DB>where
DB: ParallelDatabase,

source

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter. Read more

source

impl<DB> Deref for Snapshot<DB>where
DB: ParallelDatabase,

type Target = DB

The resulting type after dereferencing.

source

fn deref(&self) -> &DB

Dereferences the value.
