Crate webylib_macros 

Procedural macros for webylib.

Three macros land here:

• #[wallet_op] — generates lock/run-effect/emit-event/persist plumbing for a wallet operation. Mirrors webycash-server’s #[gen_server].
• #[asset_storage] — generates per-asset CRUD on the Store trait from a struct definition.
• #[ffi_export] — generates the extern "C" shim, error-code marshaling, opaque-handle lifecycle, and async-callback bridging for the FFI layer. This is the macro that replaces the legacy 22K-LOC handwritten src/ffi/wallet_ops.rs with one source of truth.

Attribute Macros

asset_storage

#[asset_storage] — placeholder that re-emits the input unchanged. Generates per-asset CRUD on the Store trait when populated.

ffi_export

Attribute macro that takes an async (or sync) Rust function and emits a matching extern "C" shim.

wallet_op

#[wallet_op] — placeholder that re-emits the input unchanged. Real plumbing (lock/run/persist) lands when webylib-core operations migrate from webylib/src/wallet/operations.rs.
