1//! High-level transaction intents.
2//!
3//! Intents describe *what* a transaction should accomplish without requiring the caller to
4//! manually manage coin selection or object resolution. When the transaction is built with
5//! [`TransactionBuilder::build`](crate::TransactionBuilder::build), registered resolvers
6//! communicate with the network to fill in the details.
7//!
8//! Currently the only built-in intent is [`CoinWithBalance`], which requests a coin of a
9//! given type and amount.
