Struct SpendIntent 

pub struct SpendIntent {
    pub delegation_id: String,
    pub nonce: u64,
    pub amount_cents: u64,
    pub merchant_id: String,
    pub category: String,
    pub memo: String,
}

Fields

delegation_id: String

目标委托 id(必须已注册,否则 UnknownDelegation 拒)。

nonce: u64

防重放 nonce,agent 作用域内单调递增;0 非法(对齐 Mist「spend_nonce > 0」)。

amount_cents: u64

本笔金额,单位分。0 非法;溢出在闸内按预算阶段拒绝。

merchant_id: String

商户 id(京东 SKU 店铺/商户标识,开放平台侧语义,闸不解析)。

category: String

消费类别(自由文本标签,落审计用;Mist 是哈希白名单,P0 不做白名单)。

memo: String

备注(人类可读,落审计;空串 = 无备注)。

pub fn validate(&self) -> Result<(), CoreError>

意图自身合法性(闸判定前先过这道,非法意图不必看委托状态)。
