Expand description
Implementation of the NifRecord
macro that lets the user annotate a struct that will
be translated directly from an Elixir struct to a Rust struct. For example, the following
struct, annotated as such:
ⓘ
#[derive(Debug, NifRecord)]
#[tag = "record"]
struct AddRecord {
lhs: i32,
rhs: i32,
}
This would be translated by Rustler into:
defmodule AddRecord do
import Record
defrecord :record, [lhs: 1, rhs: 2]
end
