Attribute Macro program 

#[program]

Generates code for turning a Rust impl block into a Sails program based on a set of public methods of the block. See documentation for details.

The macro can be customized with the following arguments:

• crate - specifies path to the sails-rs crate allowing the latter to be imported with a different name, for example, when the sails-rs create is re-exported from another crate.
• handle_signal - specifies a path to a function that will be called after standard signal handling provided by the gstd crate.
• payable - specifies that the program can accept transfers of value.

The macro also accepts a handle_reply attribute that can be used to specify a function that will handle replies. This function should be defined within the program and accepts &self. The function will be called automatically when a reply is received.

Examples

mod my_program {
    use sails_rs::program;

    pub struct MyProgram;

    #[program(payable)]
    impl MyProgram {
        pub fn default() -> Self {
            Self
        }

        pub fn from_seed(_seed: u32) -> Self {
            Self
        }

        #[handle_reply]
        fn inspect_reply(&self) {
            // Handle reply here
        }
    }
}
