anchor_generate_cpi_crate/
lib.rs

1//! Generates a crate for cross-program invocations to an Anchor program from a JSON IDL.
2//!
3//! # Usage
4//!
5//! In a new crate, write:
6//!
7//! ```skip
8//! anchor_gen::generate_cpi_crate!("../../examples/govern-cpi/idl.json");
9//!
10//! declare_id!("GjphYQcbP1m3FuDyCTUJf2mUMxKPE3j6feWU1rxvC7Ps");
11//! ```
12//!
13//! This will generate a fully functional Rust CPI client for your IDL.
14//!
15//! More examples can be found in the [examples/](https://github.com/saber-hq/anchor-gen/tree/master/examples) directory.
