Trait FromIn 

pub trait FromIn<'a, T>: Sized {
    // Required method
    fn from_in(value: T, allocator: &'a Allocator) -> Self;
}

This trait works similarly to the standard library From trait.

It comes with a similar implementation containing blanket implementation for IntoIn, reflective implementation and a bunch of primitive conversions from Rust types to their arena equivalent.

Required Methods

fn from_in(value: T, allocator: &'a Allocator) -> Self

Converts to this type from the input type within the given allocator.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
