Function rustler_codegen::nif_map [−][src]
pub fn nif_map(input: TokenStream) -> TokenStream
Implementation of a macro that lets the user annotate a struct with NifMap
so that the
struct can be encoded or decoded from an Elixir map. For example, the following struct
annotated as such:
#[derive(NifMap)]
struct AddMap {
lhs: i32,
rhs: i32,
}
Given the values 33 and 21 for this struct, this would result, when encoded, in an elixir map with two elements like:
%{lhs: 33, rhs: 21}
