Trait jlrs::convert::into_julia::IntoJulia[−][src]

pub unsafe trait IntoJulia: Sized + 'static {
    fn julia_type<'scope>(_: Global<'scope>) -> DataTypeRef<'scope>;
}
Expand description

Trait implemented by types that can be converted to a Julia value in combination with Value::new. This trait can be derived, it’s recommended to use JlrsReflect.jl to ensure it’s implemented correctly.

If you do choose to implement it manually, you only need to implement the julia_type method which must return the DataType of the type this data will have in Julia. The layout of this type and the type in Rust must match exactly. Incompatible layouts will lead to UB. Note that the type in Rust must always be #[repr(C)].

Required methods

Returns the associated Julia type of the implementor. The layout of that type and the Rust type must match exactly, otherwise the trait is implemented incorrectly.
