Struct WriteTransactionGuard 

pub struct WriteTransactionGuard { /* private fields */ }

RAII token proving “I hold the write-transaction slot for this store.” See the module doc for the full rationale.

Implementations

impl WriteTransactionGuard

pub fn acquire(db_context: &DbContext, site: &'static str) -> Result<Self>

Claim the write-transaction slot for db_context’s store. site names the call site, used only in the panic/error message.

Panics

In debug builds, panics immediately if this store’s slot is already held — some other write transaction is already open on it. Turns the silent-data-loss failure mode this guards against into a loud one, at the exact call site that introduced the second writer (or, for a same-thread re-entry, the call site that never released its own previous guard — see the module doc).

Errors

In release builds, returns an error instead of panicking — a shipped build should degrade to a reported failure, not abort the process.

Trait Implementations

impl Debug for WriteTransactionGuard

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

Formats the value using the given formatter.

impl Drop for WriteTransactionGuard

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.
