Methods from Deref<Target = DbWrite<Kind>>§
pub async fn conn_write_permit(&self) -> impl Future<Output = PConnPermit>
pub async fn async_commit<E, R, F>( &self, f: F ) -> impl Future<Output = Result<R, E>>where E: From<DatabaseError> + Send + 'static, F: FnOnce(&mut Transaction<'_>) -> Result<R, E> + Send + 'static, R: Send + 'static,

sourcepub async fn async_commit_in_place<E, R, F>(
&self,
f: F
) -> impl Future<Output = Result<R, E>>where
E: From<DatabaseError>,

pub async fn async_commit_in_place<E, R, F>( &self, f: F ) -> impl Future<Output = Result<R, E>>where E: From<DatabaseError>, F: FnOnce(&mut Transaction<'_>) -> Result<R, E>, R: Send,
If possible prefer async_commit as this is slower and can starve chained futures.

§fn to_subset(&self) -> Option<SS>
fn to_subset(&self) -> Option<SS>
The inverse inclusion map: attempts to construct
self
from the equivalent element of its
superset. Read more§fn is_in_subset(&self) -> bool
fn is_in_subset(&self) -> bool
Checks if
self
is actually part of its subset T
(and can be converted to it).§fn to_subset_unchecked(&self) -> SS
fn to_subset_unchecked(&self) -> SS
Use with care! Same as
self.to_subset
but without any property checks. Always succeeds.§fn from_subset(element: &SS) -> SP
fn from_subset(element: &SS) -> SP
The inclusion map: converts
self
to the equivalent element of its superset.§impl<T> Upcastable for Twhere
