drfit-idl-gen

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.

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