Struct DbConflictCode 

#[repr(transparent)]
pub struct DbConflictCode(pub i32);

Reason a storage delta could not be applied during two-phase commit. These are the nondeterministic failures of try_push_new_subtransaction: any of them causes ExecResultTxNonDeterministicError, and the transaction is excluded from the block. Codes are intentionally coarse; finer-grained detail may be added later behind a debug-only extension.

Implementations

impl DbConflictCode

pub const ExclusiveLockDenied: DbConflictCode

Exclusive-lock collision: the key is exclusively locked by another transaction (committed or concurrent), an exclusive lock could not be acquired because other transactions hold the key, or an exclusive-lock flag was used on a key type that does not support it.

pub const TypeMismatch: DbConflictCode

Two transactions created different item types at the same key.

pub const ValueMismatch: DbConflictCode

Two transactions wrote irreconcilable values of the same type at the same key: different bytestrings, different nnint base values, different auth-data bases, or different contract / deployment hashes.

pub const BoundsExceeded: DbConflictCode

A nonnegative int would go below zero given the deltas in this block. A native-token balance that cannot cover its debits reports InsufficientFunds instead.

pub const Overflow: DbConflictCode

Integer overflow combining deltas on a nonnegative int or balance.

pub const ReplayProtection: DbConflictCode

Replay-protection conflict: uniquifier expired, already consumed (in a prior block or by a concurrent transaction), or consumed twice by this transaction.

pub const QueueConsumer: DbConflictCode

A retrocausal queue already has a consumer in this block.

pub const CapacityExceeded: DbConflictCode

A per-item capacity limit was hit: replay-cache active heights or nonces, retrocausal-queue block entries, or auth signer slots.

pub const InsufficientFunds: DbConflictCode

The native-token balance at the diagnostic’s address cannot cover the debits in this block, or a newly created balance item cannot cover its own storage cost. Storage written under a contract’s address is charged to that contract’s balance, so a deployment reports this at the new contract’s address when it holds no native tokens.

pub const DuplicateSigner: DbConflictCode

An auth-data change would register a public key in a slot while another slot of the same address already holds that key, whether committed or set by the same change. The table would count one key’s weight twice, so the change is refused.
