Struct PrewarmedDatabasePool 

pub struct PrewarmedDatabasePool { /* private fields */ }

Opt-in bounded queue of never-used disposable databases cloned from one template.

Implementations

impl PrewarmedDatabasePool

pub fn capacity(&self) -> usize

Returns the configured database-slot bound.

pub fn status(&self) -> PrewarmPoolStatus

Returns a point-in-time view of the bounded queue state.

pub async fn database(&self) -> Result<DatabaseLease>

Leases one never-used database from the ready queue.

A ready token is reserved before downstream application capacity. If application admission or this pool is closed, or if this future is cancelled, the token is returned and the idle database remains in the queue until pool cleanup consumes it.

pub async fn shutdown(self) -> Result<()>

Closes this queue, drops all idle databases, and waits for lifecycle work accepted before the resulting server-scoped cleanup barrier.

Leases still owned by callers are not revoked. They remain responsible for their own cleanup and will not trigger a refill after this call.

Trait Implementations

impl Clone for PrewarmedDatabasePool

fn clone(&self) -> Self

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PrewarmedDatabasePool

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

Formats the value using the given formatter.

impl Drop for PrewarmedDatabasePool

fn drop(&mut self)

Executes the destructor for this type.

fn pin_drop(self: Pin<&mut Self>)

🔬This is a nightly-only experimental API. (pin_ergonomics)

Execute the destructor for this type, but different to Drop::drop, it requires self to be pinned.
