Aztec macros

All Aztec macros

In addition to the function macros in Noir, Aztec also has its own macros for specific functions. An Aztec contract function can be annotated with more than 1 macro. It is also worth mentioning Noir's unconstrained function type here (Noir docs page).

• #[aztec] - Defines a contract, placed above contract ContractName{}
• #[external("...")] - Whether the function is to be callable from outside the contract. There are 3 types of external functions: #[external("public")], #[external("private")] or #[external("utility")] - The type of external defines whether the function is to be executed from a public, private or utility context (see Further Reading)
• #[initializer] - If one or more functions are marked as an initializer, then one of them must be called before any non-initializer functions
• #[noinitcheck] - The function is able to be called before an initializer (if one exists)
• #[view] - Makes calls to the function static
• #[only_self] - Available only for external functions - any external caller except the current contract is rejected.
• #[internal] - NOT YET IMPLEMENTED - Function can only be called from within the contract and the call itself is inlined (e.g. akin to EVM's JUMP and not EVM's CALL)
• #[note] - Creates a custom note
• #[storage] - Defines contract storage
