Struct tea_sdk::actor_txns::context::TokenContext

pub struct TokenContext {
    pub tid: TokenId,
    pub tsid: Tsid,
    /* private fields */
}

TokenContext implement the context trait it store all changes a txn made before actually commit to state When there is a read inside a txn logic, it will check its context first, in case there is a prior change made by prior logic when write, all write in context without changing the actual state, until final commit if commit fail, nothing will change in the state. if commit succeed, everything will be write into the state.

Fields

tid: TokenId

Token Id, this context has and has only one tokenid related If a transaction need to read/write multiple token (FT or NFT) it needs to start multiple contexts. Every context associate to a FT/NFT token

tsid: Tsid

the tsid of the txn the context is associated. Every context is associated with a specific txn
