Struct AccessToken 

pub struct AccessToken { /* private fields */ }

Domain Entity: AccessToken

Represents a reader’s access to a specific article. Access tokens are issued after successful payment and grant time-limited access.

Domain Rules:

• Token is tied to a specific article and reader wallet
• Token has an expiration date (default 30 days)
• Token can be revoked (e.g., on refund)
• Token cannot be transferred to another wallet
• Expired or revoked tokens do not grant access

Implementations

impl AccessToken

pub fn new_paid( tenant_id: TenantId, article_id: ArticleId, creator_id: CreatorId, reader_wallet: WalletAddress, transaction_id: TransactionId, token_hash: String, ) -> Result<Self>

Create a new access token for a paid transaction

pub fn new_with_duration( tenant_id: TenantId, article_id: ArticleId, creator_id: CreatorId, reader_wallet: WalletAddress, transaction_id: Option<TransactionId>, access_method: AccessMethod, token_hash: String, duration_days: i64, ) -> Result<Self>

Create a new access token with custom duration

pub fn new_free( tenant_id: TenantId, article_id: ArticleId, creator_id: CreatorId, reader_wallet: WalletAddress, token_hash: String, duration_days: i64, ) -> Result<Self>
