Struct ApprovalStatement 

pub struct ApprovalStatement {
    pub type_: String,
    pub timestamp: String,
    pub approver: String,
    pub subject: SubjectRef,
    pub description: Option<String>,
    pub expires_at: Option<String>,
    pub delegatable: bool,
    pub nonce: String,
    pub scope: Option<ApprovalScope>,
    pub policy_ref: Option<String>,
    pub meta: Option<Value>,
}

Records that an approver authorised an intent or action.

The nonce field is the cornerstone of approval security: the consuming ActionStatement must echo the same nonce in its approval_nonce field. This cryptographically binds each approval to exactly one action (or max_actions actions when set), preventing approval reuse.

Fields

type_: String

timestamp: String

approver: String

DID-style approver URI. e.g. “human://alice”

subject: SubjectRef

description: Option<String>

expires_at: Option<String>

ISO 8601 expiry timestamp. None means no expiry.

delegatable: bool

Whether the receiving actor may re-delegate this approval.

nonce: String

Random token. The consuming ActionStatement must set its approval_nonce field to this value. Generated by the SDK if not provided by the caller.

scope: Option<ApprovalScope>

policy_ref: Option<String>

meta: Option<Value>
