Derive Macro rustler::NifException
source · #[derive(NifException)]
{
// Attributes available to this derive:
#[module]
#[rustler]
}
Expand description
Derives implementations for the Encoder
and Decoder
traits
which convert between an Elixir exception and a Rust struct.
For example, annotate the following struct:
ⓘ
#[derive(Debug, NifException)]
#[module = "AddException"]
pub struct AddException {
message: String,
}
Write the corresponding Elixir exception definition:
defmodule AddException do
defexception message: ""
end
Then the traits Encoder
and Decoder
are derived automatically for your Rust struct
such that you can use the Elixir exception definition for it.
