CoreError

Enum CoreError 

Source
pub enum CoreError {
Show 13 variants InvalidDelegation(String), InvalidIntent(String), UnknownDelegation(String), DuplicateDelegation(String), LedgerOverflow(String), CommitRejected(String), WalIo(String), WalLocked { path: String, message: String, }, WalBadLine { line: u64, message: String, }, WalChainBroken { line: u64, message: String, }, WalMismatch { line: u64, message: String, }, AnchorInvalid(String), AnchorMismatch(String),
}

Variants§

§

InvalidDelegation(String)

委托注册被拒:字段非法(空 id / 预算为 0 / 有效期倒挂等)。fail-closed:宁可注册失败。

§

InvalidIntent(String)

意图非法:金额或 nonce 为 0、必填字段为空。

§

UnknownDelegation(String)

引用了不存在的委托(撤销/查询)。

§

DuplicateDelegation(String)

委托 id 重复注册。

§

LedgerOverflow(String)

账本累计溢出(u64)。状态异常,fail-closed:宁可报错也不回绕把巨额记成小额。

§

CommitRejected(String)

在闸未放行的情况下调用了 commit(API 误用,程序员错误)。 正常流程是 evaluate → (写审计) → commit;直接 commit 会被这里拦下。

§

WalIo(String)

WAL 打开/读写失败。

§

WalLocked

单写者锁被占:同一份 WAL 已有另一个活着的写进程。fail-closed 拒启—— 两个闸共写一份审计 = 预算硬上限失效、同一 nonce 跨进程放行两次。

Fields

§path: String
§message: String
§

WalBadLine

WAL 里有一行读不懂(半行 JSON / 空行 / 未知结构)。绝不静默跳过

Fields

§line: u64
§message: String
§

WalChainBroken

WAL 完整性链断裂(seq 与物理行号不符 / prev 与按前文重算的链值不符)。 这是日志被改(改字段/删行/重排/复制)的痕迹,fail-closed 拒读拒续写。

Fields

§line: u64
§message: String
§

WalMismatch

回放时重算结果与记录不一致(日志被改 / 实时与回放口径漂移)。fail-closed 停机。

Fields

§line: u64
§message: String
§

AnchorInvalid(String)

审计锚点文件非法:格式/字段读不懂,或 MAC 与所有者密钥对不上(锚点不是 所有者签的,或锚点本身被改)。fail-closed:不可信的锚点比没有锚点更危险。

§

AnchorMismatch(String)

当前 WAL 与合法锚点不符:整体截尾(行数不足)或被锚定的前缀内容被改。 这是 W-21 完整性链已知边界(尾行篡改/截尾本地验不住)的抓法。
