Struct Checkout 

pub struct Checkout<S = SnowflakeSession> { /* private fields */ }

A session checked out of a pool.

Return it with SessionPool::checkin or drop it with SessionPool::discard. If it is dropped without either (a panic or early return between checkout and checkin), its Drop guard removes the orphaned slot so the member doesn’t linger as phantom-busy.

Implementations

impl<S> Checkout<S>

pub fn session(&self) -> &S

The checked-out session.

pub fn base(&self) -> &QueryContext

The session’s base (creation-time) context.

pub fn current(&self) -> &QueryContext

The context currently applied to the session.

pub fn id(&self) -> u64

The session member id.

Trait Implementations

impl<S> Drop for Checkout<S>

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.
