Struct SsaCommitmentGuard 

pub struct SsaCommitmentGuard<S: PixSpec + Clone> {
    owned: Option<(Arc<SsaReconstructor<S>>, SsaId<<S as PixSpec>::Pseudonym>)>,
}

Ownership of an Exit SSA commitment, released when dropped.

Registering an Exit commitment is the first fallible step of many: the request still has to be encoded, sent, and answered. Every early return between here and the point where a permanent owner takes over would otherwise strand the commitment in the reconstructor until its own lifetime expired, and a stranded commitment is not inert — its SsaId is occupied, so a retry at the same index is rejected as a duplicate.

Move-only by design: no Clone, no Copy, so there is exactly one release point. A success path hands ownership on with disarm rather than letting the guard fall out of scope.

Dropping releases the registration without retiring the SSA, so the same index can be requested again — see SsaReconstructor::release_abandoned_commitment for why that distinction is load-bearing.

Fields

owned: Option<(Arc<SsaReconstructor<S>>, SsaId<<S as PixSpec>::Pseudonym>)>

None once disarmed, which is the only state in which Drop does nothing.

Implementations

impl<S: PixSpec + Clone> SsaCommitmentGuard<S>

pub fn ssa_id(&self) -> Option<&SsaId<S::Pseudonym>>

The SSA this guard owns, or None if it has been disarmed.

pub fn disarm(self) -> Option<SsaId<S::Pseudonym>>

Gives up ownership without retiring, returning the SSA that is now the caller’s to release.

Returns None if the guard was already disarmed.

Trait Implementations

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

Formats the value using the given formatter.

impl<S: PixSpec + Clone> Drop for SsaCommitmentGuard<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.
