Macros

List of macros supporting the sv::msg_attr attribute:

Usage

Use the sv::msg_attr above any of the methods marked with #[sv::msg(..)] attribute.

pub struct Contract;
 
#[contract]
#[sv::msg_attr(instantiate, derive(MyDeriveMacro))]
#[sv::msg_attr(instantiate, MyAttributeMacro(param))]
#[sv::msg_attr(instantiate, AttributeForMacro(param1, param2))]
impl Contract {
    pub fn new() -> Self {
        Self
    }
 
    #[sv::msg(instantiate)]
    fn instantiate(&self, ctx: InstantiateCtx) -> StdResult<Response> {
        Ok(Response::new())
    }
}

The contract and interface macros will decorate the message with the attributes/macros provided in sv::msg_attr.
