sui-transaction-builder 0.3.1

//! High-level transaction intents.
//!
//! Intents describe *what* a transaction should accomplish without requiring the caller to
//! manually manage coin selection or object resolution. When the transaction is built with
//! [`TransactionBuilder::build`](crate::TransactionBuilder::build), registered resolvers
//! communicate with the network to fill in the details.
//!
//! The built-in intents are [`Coin`] (requesting a `Coin<T>`) and [`Balance`] (requesting a
//! `Balance<T>`). Both are handled by the same resolver so that mixed requests for the same
//! coin type are accounted for together.
