Crate rustler_codegen

Macros

• init
  Initialise the Native Implemented Function (NIF) environment and register NIF functions in an Elixir module.

Attribute Macros

• nif
  Wrap a function in a Native Implemented Function (NIF) implementation, so that it can be called from Elixir, with all encoding and decoding steps done automatically.

Derive Macros

• NifException
  Derives implementations for the Encoder and Decoder traits which convert between an Elixir exception and a Rust struct.
• NifMap
  Derives implementations for the Encoder and Decoder traits which convert between Rust struct and an Elixir map.
• NifRecord
  Derives implementations for the Encoder and Decoder traits which convert between a Rust struct and an Elixir record.
• NifStruct
  Derives implementations for the Encoder and Decoder traits which convert between an Elixir struct and a Rust struct.
• NifTaggedEnum
  Implementation of the NifTaggedEnum macro that lets the user annotate an enum that will generate elixir values when encoded. This can be used for any rust enums and will generate three types of values based on the kind of the enum. For example from the test code:
• NifTuple
  Derives implementations for the Encoder and Decoder traits which convert between a Rust struct and an Elixir tuple.
• NifUnitEnum
  Derives implementations for the Encoder and Decoder traits which convert between an enum and a union of elixir atoms.
• NifUntaggedEnum
  Derives implementations for the Encoder and Decoder traits which convert between a Rust enum and a union of Elixir types.
