Macros

init

Implementation of a Native Implemented Function (NIF) macro that lets the user annotate a function that will be wrapped in higer-level NIF implementation.

Attribute Macros

nif

Implementation of a Native Implemented Function (NIF) macro that lets the user annotate a function that will be wrapped in higer-level NIF implementation.

Derive Macros

NifException

Implementation of the NifException macro that lets the user annotate a struct that will be translated directly from an Elixir exception to a Rust struct. For example, the following struct, annotated as such:

NifMap

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:

NifRecord

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:

NifStruct

Implementation of the NifStruct 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:

NifTuple

Implementation of a macro that lets the user annotate a struct with NifTuple so that the struct can be encoded or decoded from an Elixir tuple. For example, the following struct annotated as such:

NifUnitEnum

Implementation of the NifUnitEnum macro that lets the user annotate an enum with a unit type that will generate elixir atoms when encoded

NifUntaggedEnum

Implementation of the NifUntaggedEnum macro that lets the user annotate an enum that will generate elixir values when decoded. This can be used for rust enums that contain data and will generate a value based on the kind of data encoded. For example from the test code:
