An overview of Functions
Functions are units of execution in the AssemblyLift framework. They are grouped into services, and are themselves structured according to the chosen language (e.g with Rust each function is a Cargo crate).
Each function is compiled to a WebAssembly module, compatible with the AssemblyLift ABI.
An AssemblyLift Function is an executable containing a handler, which is the entrypoint of the Function (similar to a main method in a regular application). A Function usually receives some input which is passed to the handler as an argument; the shape of this input will depend on the Function. The Function should return by indicating either success or an error to the runtime, though the Function is not required to return any specific data.
You can create a new function in an existing service with the
$ asml make function myservice.myfunction
myserviceis the name of the service in which you would like to make the function named
