Struct salsa::Snapshot[−][src]

pub struct Snapshot<DB: ?Sized> where
    DB: ParallelDatabase,  { /* fields omitted */ }
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

impl<DB> Snapshot<DB> where
    DB: ParallelDatabase, [src]

pub fn new(db: DB) -> Self[src]

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

Trait Implementations

impl<DB: Debug + ?Sized> Debug for Snapshot<DB> where
    DB: ParallelDatabase, [src]

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

Formats the value using the given formatter. Read more

impl<DB> Deref for Snapshot<DB> where
    DB: ParallelDatabase, [src]

type Target = DB

The resulting type after dereferencing.

fn deref(&self) -> &DB[src]

Dereferences the value.
