Trait FromHostValue 

pub trait FromHostValue: Sized {
    // Required methods
    fn from_host_value(v: &Value) -> Self;
    fn host_type() -> HostType;
}

Extracts a Rust argument from a Value for a registered host closure.

Required Methods

fn from_host_value(v: &Value) -> Self

fn host_type() -> HostType

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
