Trait FromLive 

pub trait FromLive: Sized {
    // Required method
    fn from_live(value: Value) -> Result<Self, String>;
}

What a host function’s argument can be made from.

Required Methods

fn from_live(value: Value) -> Result<Self, String>

The value as this type, or why it cannot be.

Dyn Compatibility

This trait is not dyn compatible.

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