Trait jlrs::convert::unbox::Unbox[−][src]

pub unsafe trait Unbox {
    type Output: Sized + Clone;
    unsafe fn unbox(value: Value<'_, '_>) -> Self::Output { ... }
}
Expand description

Trait implemented by types that can be extracted from a Julia value in combination with Value::unbox and Value::unbox_unchecked. This trait can be derived, it’s recommended to use JlrsReflect.jl to ensure it’s implemented correctly. All wrappers generated by JlrsReflect.jl will implement this trait and ValidLayout, which checks if the conversion is valid at runtime.

If you do choose to implement it manually, you only need to provide the associated Output type if the type matches the layout of the data in Julia, the default implementation of unbox dereferences the value as &Self::Output and clones it. If this implementation is incorrect it can be overridden.

Associated Types

Provided methods

Unbox the value as Self::Output.

Safety: The default implementation assumes that Self::Output is the correct layout for the data that value points to.
