⚠️ for drift-rs there's no need to run this manually. The build.rs script will trigger it.

Generates rust anchor structs from IDL json This is implemented rather than another project for a couple reasons:

  1. #[repr(C)] other IDL generation tools do not provide the ability to market structs with repr(C) which is necessary for ffi functionality throught the drift-rs project.
  2. does not rely on anchor vendored solana crates. anchor is pinned to older versions of the solana crates. drift-rs seeks to be readily upgradable to use lastest solana crates.

Dev Note ⚠️

  • An important assumption in this code is that the underlying types (serialization and deserialization) does not change among solana crate versions i.e solana_sdk_1.16::Pubkey == solana_sdk_2.x::Pubkey == anchor_lang::solana_sdk::Pubkey this allows the generated IDL code to ignore the anchor version of crates.

lib.rs:

Auto-generated IDL types, manual edits do not persist (see crates/drift-idl-gen)

IDL instruction types IDL types IDL Account types IDL error types IDL event types
